With Judas turning to self-execution, righting the wrong he did(betraying Jesus), can we forgive Judas?

We should, but God can't. He is as bound by eternal laws as we are by natural laws.  Jesus Christ called Judas Iscariot both a devil and a son of Perdition.  That's good enough for me.

Yes, we can. ....................

Jesus spoke clearly of the fate of Judas:

Matthew 26:24-25, (also Mark 14:21)

"24 The Son of man goeth as it is written of him: but woe unto that man by whom the Son of man is betrayed! it had been good for that man if he had not been born.

25 Then Judas, which betrayed him, answered and said, Master, is it I? He said unto him, Thou hast said."

Now if Judas was to be forgiven and go to Heaven then the joy of eternal life in Heaven would infinitely outweigh any bad thing which had happened to him before. And it would not be true that it would have been better for him to have not been born.  Even if one believed in the Roman Catholic doctrine of purgatory (I do not), at the end of purgatory he would have eternal and everlasting joy.

Judas' suicide should be contrasted to Paul/Saul's missionary activity. Paul had set his hand against the early Christian church in a major way. But when he repented he didn't kill himself. Instead he worked hard to build up the Christian church.

Judas is the one person whom scripture explicitly says was certainly damned.

In Christian mythology, everything is ordained by their god. It was all part of the master plan if you believe the inconsistencies of the Bible.

Judas paid the price for his sin, yes. (Romans 6:23) But, it was a sin that was deliberate and didn’t have to be committed necessarily by him, hence why Jesus said it would’ve been better if Judas wouldn’t have been born at all. (Mark 14:21) While it’s true Jesus forgave some of those that put him to death, those specific men knew not what they were doing, but Judas knew full well what he was doing, and by doing what he did he blasphemed the spirit, which is a sin there’s no forgiveness for. (Mark 3:29)

I think so as well . bad light they put on him in the myth . I like the serpent ' She was telling the truth in the garden . Sure Adam did not die . As far as that myth 

" If nothing or no one had ever died *how did Adam know what die was when god supposedly mythically was teaching them to avoid knowledge of the tree of .

Besides being a myth  How does Skydaddy teach children what to do without reference ? 

He only did was he was directed to do by God.  He fulfilled his purpose.  Without his betrayal, there would be no Christianity.
