Honestly I've been seeing some users saying vampire mikaela was sooooo selfish, and it really confuses me. Like, the orphans who were killed were mikas family too! But yet he's not rushing into this resurrection plan blindly (like yuu is!), because he knows about what happened last time a catastrophe like that happened. 1/3 of the human population were wiped out!
He's come to peace with the death of the orphans, but in exchange he just puts all of the self hate and blame on himself. The important thing is, he's not willing to sacrifice ANYONE for his desires. He might want his family back just as much as yuu does, but the key difference is that he's doesn't want to risk the lives of others. He's one of the most SELFLESS characters in the story. Whereas with yuu and guren the philosophy is, I don't care about who has to die, as long I get what I want. Which sounds really childish and selfish
