@Kamelpov didn't you read chapter 1? He was always a villain for personal reasons and in this chapter he said that he doesn't really care about himself since his future self would stop him if he made a wrong move. He doesn't care about world domination, he was always fueled by personal vendetta.
"At least make sure your enemy is dead"
Bruhh, he stabbed you, cut your arm and beheaded you. I'm pretty sure most would think you're dead at that point.
@Siikalahna maybe because he needed intel on why the attack was happening ya dumdum
