Aaah.... The usual Netizen... Just accept the "fact" they saw in the media without actually do some digging. They didn't know or remember how our MC's parents rage the same way these... "parents" rage. They didn't know or remember how all this time, our MC just want to kill those kids, but the so called "Police and Armies" is used by these "parents" as a meat wall to block him. Even if he didn't want to kill those so called "people who are doing their job", when every last one of them are "ordered" to block or even kill him, what do they expect him to do? And these netizen didn't even think of how much time, work, and money needed to actually be able to kill the president's daughter and 6 other kids "silently". He didn't even do anything to others, including whose who talk bad to him (yet). He only attack those who blocked him. As always, Netizen likes to say something first before thinking.
I didn't say what did is correct. But i can't just diss MC for being crazy when he is obviously berserking.
... In which, it might actually be worse than crazy.
