We humans are predators and as such all of us have the capacity to kill. Some of us have practiced and studied techniques to do this so we would be better at it than a novice. For some it is reflexive on proper stimulus.
Personally, I would kill someone who tried to kill or harm me, a member of my family or someone who was threatening others with death. As an advanced martial artist and weapons expert who pretty much always goes armed, I am quite capable of killing someone if I must. I would rather not, however, and would not, if that could be avoided.
I don't really think this is something to be taken lightly either.
Remember what I said about having a very suburban perspective?![]()
There's a lot of reasons why people become serial killers, and with your skills I hope you never find one of those reasons.
