I don't really agree with those complaining about the personality shift. He's kind to most people, but most people aren't trying to harm him. He also asked death for a strong will to see through his plans, and he's suffered a great deal of torture. So he should have a hard side to him. Most people are not simple and have different faces they show to different people in different situations.0
I agree on the other comments the shift of character is too abrupt and too much. It would be realistic if he just knock them away with a wave of magic and throw a flashbang like spell and left, making the MC to the others look strong and mysterious while retaining his character. you could just then write a monologue of his thoughts. Just my comment and opinion and nothing else.
