Becoming the Villain Again

A strong and talented soul was made and as usual for newly created souls, went to reincarnate. This soul was someone who was preordained to benefit society in their world, in some way. As a world renowned doctor, a genius pianist and artist, a natural actor, a righteous and compassionate general, an assassin who only kills evil, and a hacker who exposed hidden crimes and gave justice to their victims, etc. But something unknown messed with his fate.  The doctor created a zombie virus to destroy the world, the pianist was driven insane, the actor was killed earlier than expected and was hated as a coward, the general became a mafia lord who killed people without blinking, the assassin was molded into an emotionless doll who only knew to do as ordered, and the hacker only cared about entertaining himself even if he toyed people to death. All of them had unexpectedly become a villain. A system who kept the multiverse in check wanted to stop him from continuing like this and help him, but it was already too late. His soul had splintered into six parts from his six miserable lives. So the system decided to let him experience happiness in different worlds to fix and fuse him back together. The system was satisfied with their choice until they saw... "Why are they becoming the villain again!?"
