Do God forgives murder and rape?

God will forgive you if you repent of your sin and receive the Holy Spirit. Part of that repentance involves turning yourself in to the authorities and facing the earthly consequences for your actions.

No. He can forgive the murderer and the rapists if they repent, accept Jesus.

YES .

Forgiveness doesn't exist.

Repentance may be on a collective basis as well as an individual basis. Thus, Jonah’s preaching caused the entire city of Nineveh, from the king down to “the least one of them,” to repent, for in God’s eyes they were all sharers in the wrong. (Jon 3:5-9; compare Jer 18:7, 8.) The entire congregation of returned Israelites, under Ezra’s prompting, acknowledged community guilt before God, expressing repentance through their princely representatives. (Ezr 10:7-14; compare 2Ch 29:1, 10; 30:1-15; 31:1, 2.) The congregation at Corinth expressed repentance over having tolerated in their midst a practicer of gross wrongdoing. (Compare 2Co 7:8-11; 1Co 5:1-5.) Even the prophets Jeremiah and Daniel did not completely exempt themselves of guilt when confessing the wrongdoing of Judah that led to her overthrow.—La 3:40-42; Da 9:4, 5.

What true repentance requires. Repentance involves both mind and heart. The wrongness of the course or act must be recognized, and this requires an acknowledgment that God’s standards and will are righteous. Ignorance or forgetfulness of his will and standards is a barrier to repentance. (2Ki 22:10, 11, 18, 19; Jon 1:1, 2; 4:11; Ro 10:2, 3) For this reason Jehovah mercifully has sent prophets and preachers to call persons to repentance. (Jer 7:13; 25:4-6; Mr 1:14, 15; 6:12; Lu 24:27) By means of the publishing of the good news through the Christian congregation, and particularly from the time of the conversion of Cornelius forward, God has been “telling mankind that they should all everywhere repent.” (Ac 17:22, 23, 29-31; 13:38, 39) God’s Word—whether written or spoken—is the means for ‘persuading’ them, convincing them of the rightness of God’s way and the wrongness of their own ways. (Compare Lu 16:30, 31; 1Co 14:24, 25; Heb 4:12, 13.) God’s law is “perfect, bringing back the soul.”—Ps 19:7.

Getting the sense with the heart. For repentance, then, there must initially be a hearing and seeing with understanding, due to a receptive heart. (Compare Isa 6:9, 10; Mt 13:13-15; Ac 28:26, 27.) Not only does the mind perceive and grasp what the ear hears and the eye sees, but more important, those repenting “get the sense of it [“the thought,” Joh 12:40] with their hearts.” (Mt 13:15; Ac 28:27) There is, therefore, not merely an intellectual recognition of the wrongness of their ways but a heart appreciation of this fact. With those already having knowledge of God, it may be a case of their ‘calling back to their heart’ such knowledge of him and his commandments (De 4:39; compare Pr 24:32; Isa 44:18-20) so that they can “come to their senses.” (1Ki 8:47) With the right heart motivation they can ‘make their mind over, proving to themselves the good, acceptable, and perfect will of God.’—Ro 12:2.

If there is faith and love for God in the person’s heart, there will be sincere regret, sadness over the wrong course. Appreciation for God’s goodness and greatness will make transgressors feel keen remorse at having brought reproach on his name. (Compare Job 42:1-6.) Love for neighbor will also make them rue the harm they have done to others, the bad example set, perhaps the way in which they have sullied the reputation of God’s people among outsiders. They seek forgiveness because they desire to honor God’s name and to work for the good of their neighbor. (1Ki 8:33, 34; Ps 25:7-11; 51:11-15; Da 9:18, 19) Repentantly they feel “broken at heart,” “crushed and lowly in spirit” (Ps 34:18; 51:17; Isa 57:15), they are “contrite in spirit and trembling at [God’s] word,” which calls for repentance (Isa 66:2), and in effect, they “come quivering to Jehovah and to his goodness.” (Ho 3:5) When David acted foolishly in the matter of a census, his “heart began to beat him.”—2Sa 24:10.

There must therefore be a definite rejection of the bad course, a heartfelt hating of it, repugnance for it (Ps 97:10; 101:3; 119:104; Ro 12:9; compare Heb 1:9; Jude 23), for “the fear of Jehovah means the hating of bad,” including self-exaltation, pride, the bad way, and the perverse mouth. (Pr 8:13; 4:24) Along with this, there must be a loving of righteousness and the firm determination to adhere to a righteous course from then on. Without both this hatred of bad and love of righteousness, there will be no genuine force to the repentance, no following through with true conversion. Thus, King Rehoboam humbled himself under the expression of Jehovah’s anger, but afterward Rehoboam “did what was bad, for he had not firmly established his heart to search for Jehovah.”—2Ch 12:12-14; compare Ho 6:4-6.

This calls for “a new heart and a new spirit” (Eze 18:31); one’s changed thinking, motivation, and aim in life produce a new frame of mind, disposition, and moral force. For the one whose life course changes, the result is a “new personality which was created according to God’s will in true righteousness and loyalty” (Eph 4:17-24), free from immorality, covetousness, as well as violent speech and conduct. (Col 3:5-10; contrast Ho 5:4-6.) For such ones God causes the spirit of wisdom to “bubble forth,” making his words known to them.—Pr 1:23; compare 2Ti 2:25.

Thus genuine repentance has real impact, generates force, moves the person to “turn around.” (Ac 3:19) Hence Jesus could say to those in Laodicea: “Be zealous and repent.” (Re 3:19; compare Re 2:5; 3:2, 3.) There is evidence of ‘great earnestness, clearing of oneself, godly fear, longing, and righting of the wrong.’ (2Co 7:10, 11) Absence of concern for rectifying wrongs committed shows lack of true repentance.—Compare Eze 33:14, 15; Lu 19:8.

Jesus said, Mark 3:28,29 28 "Truly I say to you that all things will be forgiven the sons of men, no matter what sins they commit and what blasphemies they speak. 29 But whoever blasphemes against the holy spirit has no forgiveness forever but is guilty of everlasting sin.”

If the person is repentant of their action and turns away from it. But that does not exempt them from the consequences of their action.

(If you think that forgiving them is wrong...would you prefer that they continue to murder and rape rather than turning from that?)

Some teach that grievous sin leaves a permanent stain on the soul that repentance alone cannot fully removed but can only be purged from the soul after death by God in a place of punishment called purgatory.

God forgives all who truly repent. The only unforgivable sin is that of refusing forgiveness

No, not at all.

When you invade the Will of an other person,

their heart will never disallow, forget, or totally heal from the event.

Therein, after having committed such an intentional and immoral act, there is no repentance

that has ever been established in Creation, that will afford anyone the luxury of God's forgiveness.

Repentance is for those who

steal things like candy, cars, money, alcohol, lawn mowers, and restaurant silverware .... Not lives.

Not really.

God exists only in stories. In some of these stories he forgives in some of them he is a terrorist and does not forgive anything. For instance in Deuteronomy 13:12-16.

The stories about god are not true. In reality there is no god.
