[I killed an academy player] Does this manhwa has kind, selfless, savior kind of MC?

As the title says, I just want to know if this is one of those “I will die to protect the toenail of an alien from Mars just because I’m a hero” kind of manhwa.

I read the second chapter, and the MC already declares that he’s going to save the world.

I’m not really into the “selfless hero” or “save the world” type of stories, so I’d appreciate it if someone could let me know whether this goes in that direction.
