I later learnt that he hung himself in a field he owned that no one knew about so he denied himself a burial because he knew no one would come for his body. He remained hanging on a rope until his corpse exploded and sprayed blood on the ground and lost its structural integrity to hang because of decomposition and dropped on the floor. His remains were then consumed by wild animals. The goodness of his heart had convicted him of his bad deeds and he responded to it by punishing himself in an extreme way.
In my view he was an ordinary guy like myself that became decived by an evil spirit, he thought he was doing the right thing. He thought that Jesus would use his powers to escape from the mob that had come to arrest him and would provoke him to attack the Romans.
I think every human has a capacity to become like Judas if they lean on their own understanding and think they are a good person. Don't trust your heart or your own values because you could be deceived just like Judas was.
