Doing something good with wrong intentions does not count at all if not then only a little. It's like donating to Charity but a day before that you made a huge announcement and got fame and popularity. However killing him for those reasons are too low. The only way for him to die is if he piss of the seme so much and disrupt the person with supernatural powers. Which is dumb. He should just.be glad he's still alive and run.

Good people is still unclear from the recent chapters information. Four sides for this story. The 3rd POV, the party's POV and the other party's POV. 3rd party (uke) feels respect towards the prof because he raised him during his lowest. (Good) other party's POV (seme) says the prof did it because he has an inferiority complex, uncle raising up seme so professor raising up some orphan boy to feel less superior (BAD) party's POV (prof) ???? And the truth, also unknown.

Yes, totally agree. I understand what you're saying, but that's why I'm saying that yes, if everything told until now is true, the professor's intentions in the beginning were not simply for him being good, but just to feel good with himself. But he still did a good thing for many years and actually gave a good and "normal" life to the MC. And until the chapter 44, he has not asked for anything or taken advantage of him for it. And even if his good actions had bad intentions behind, I don't think it's justifiable to simply remove the professor from Tae Joon's life by threatening to kill him. That's just extreme obsession, because people are not 100% bad or good, we make mistakes, and killing everyone who is not pure good is something I can't agree. But well, it's still just a fiction, so whatever happens, I'll keep reading, because It's really good. And also, no reason was given for why he killed his uncle and aunt If I have not missed any information.
I can accept the whole murdering parents thing, but no matter the intentions behind the professor for taking care of Tae Joon, he still raised him like his son and gave him a lot of opportunities in life and a family, so in my opinion, nothing justifies if they end up killing him. Killing your shitty parents? That's fine for me! But killing the professor is over the line.
