Deep question time!

x number of people. Depends. What can I say. By the way, that's not a deep question at all. Your just being ambiguous for the sake of ambiguity. When people can't automatically offer a logical answer to a question, they assume it's deeper that it might actually be... Is that a satisfactory answer?

well in fact in my thinking the answer is actually none since most actual humans dont care about each other and only care about how they are going to succeed

Actually many killers suffer later ... but they suffer in different ways killers can be military, law enforcement and your standard perps. Some think its glorious action to have killed others, while some contemplate if there was other ways of handling th same situation. All in all it depends on the person and if the dead individual had a family or not. Annd of course the law of "every action has a reaction" where your actions can lead to a wave of repercusions that might be immediate or in the long run. Which means ... not enough variables to give an accurate answer for every possible situation and/or outcome. So how is this a deep question? Aasking people how they feel about their own mortality would of been a more efficient question.

Now your just being negative. Most people, No matter how depressed or awful they are, Has someone who cares about them, Even if they don't deserve it. If's family, or friends, or even just co-workers. (I apologize for my language)You have to be one horrible son of a bitch to not have anyone that cares for you. My father loved his adoptive father even though he broke more of his bones then he could count during his childhood. Almost, a good 95% of people I'd wager would have at least one person that feels awful when the person dies. Now that wouldn't stop me from killing them if they attacked me or someone I care about, That's just how I was taught to fight, But I won't ignore the consequences either, It happens.

Go ask kira, I'm sure he could tell you, but first... http://i.imgur.com/04PQU4u.gif
