Okay so I’m guessing he knows his past that’s why he said “I died once.”?

he knew very well what he got into but you read episode 43. The only thing that matters to him is being powerful (that place he went was only to become powerful and the stone was stolen to amplify mana), but I think he did not get the enough power and now he's looking for people to sacrifice and become more powerful.
if he died because you can't see the suffering that happened or the tears
