Is watching movies on illegal movie websites like Putlocker a sin?

It is theft. By watching it, you are encouraging theft.

Edit: To the thief who thumbed me down, may piracy ruin you.

Thou shalt not steal.

If you believe that theft is a sin, then the answer is yes. If you believe that theft is not a sin, then it's not.

A person can live a more loving and virtuous life by reciting the rosary each day with care.

There's a reason why the uploader get the smack on the wrist, and not the watcher. It's not a sin to watch it. .

And regardless of whatever a person believes about all that, all sins are forgiven when the person believes in Jesus.

The truth is that death leads to immediate heaven or hell, depending only on whether the person believed in Jesus for eternal life, or not.

The truth is that Jesus loves you and wants to bless your life freely :) Most of all, Jesus wants you with Him forever, and not in hell. The truth is that every belief except one will lead to eternal torment in the lake of fire for every person. Because nothing pays for our sins except the death and blood of Jesus, the sacrifice of Jesus that is already accomplished by Him . Jesus loves you! The truth is that Jesus is God, and Jesus died on the cross to pay for all of our sins in full, and then Jesus resurrected from the dead. Nothing else pays for our sins, not works, not deeds, not religions. So the only way to heaven and to avoid hell, is by believing in Jesus for eternal life (John 6:47), without adding any of your own works (Romans 4:5). Believe in Jesus to take you to heaven, and you will be in heaven, no matter what, guaranteed. That easy, thanks to Jesus! Tell Jesus that you thank Him that you will be with Him in heaven when you die, because you believe in Jesus! It is too late to be saved, after death

no, Jesus was first "pirate" to multiply bread and fish.I bet those bakers and fishermen were angry how he left them without sales.

No, not usually. However, my cousin used to download the movies for free (and he did this for a lot of movies). Then, he got a letter from the government or something warning him. So, even if it gets that far, which it won’t, you will be warned before it gets serious.
