@Hell_Satan,
I give you points for reading and replying this time.
You are still too focused on whether it would be easy or not for someone to kill someone. The things you link show what I'm telling you. Since you said English is your second language and wish to end the discussion I'll
try to keep this to three points. No promises.
First, the list you gave from Dr. Mattiuzzi does not list genetic predispositions for killers. It lists types of people prone to kill based on personality or in the moment thinking or feelings. One could say personality types more likely to result in extreme violence. Even then, I would argue there are other factors that lead people to extreme violence
(upbringing, current situation, etc.).
Second, I never said that there aren't people who won't have problems. I said you think that these are the majority of human beings in existence. I will agree that many who grow up in peaceful environments are less likely to move to extreme violence in a situation, it doesn't mean they won't. In any crisis situation or when that person deems it necessary
(which depends on that person) then you will be surprised what people are capable of. Also, I used crisis situations because most stories like this would be a crisis situation for the character involved
(suddenly appearing in another world) . Yet, some authors write them as some type of pacifist with the absolute willpower over their situation and plot armor that allows them to sustain their pacifism. Even toward people who are threatening their life and the lives of those they love. Yes, there are people like that in the world. Yes, in situations like this
(crises where their lives would be threatened) they'd almost always end up dead.
Third, the National Center for Biotechnology Information study you linked proves that people would feel more guilty about killing civilians than they would soldiers. This doesn't mean they wouldn't do it if they felt threatened. The study shows they simply had a delay in deciding whether to kill the civilian. That's my point. Not everyone is going to go into a long drawn out debate about whether it was right or wrong at the time of the crisis. Stories only do that for character development. In reality, you might not know there was a delay and you're most likely in a crisis situation if you're forced to kill children or civilians. Which is exactly what I've been saying.
Overall, just be careful with generalizations and be aware your fellow man, especially the "Normal ones" wish to do good but is fully capable of doing evil.
