MY BIG QUESTION REASEARCH

I had a change of mind, so my big question is " What cause someone to kill another person?"

I did some research and found out that there are many reasons why someone would take another living persons life away. Its not ok to take another persons life but there are some examples in which it is understandable of why it had to be done.

One of the ok reasons would be mercy killing which is when someone is in so much pain and they cant do anything to fix it or there is no progress and they are just laying there hurting every dam minute, then ethier a doctor or a loved one decides to take that persons life and free their soul so they can rest in peace and not be in pain anymore

One bad reason of killing is road discipline which is usually caused by road rage or just using your vehicle as an advantage to take someone's life.

Another bad reason that drives someone to kill another person would be anger in which they have towards a certain person and all they think about is killing that person and not caring about the consequences.

Another ok reason why someone would take another persons life would be self defense. There are lots of people out there that try to take advantage of you but you have to fight your way out and its possible that you can end their lives but you have to defend yourself in any way possible.

One of the stupidest but most common killing is when some one is intoxicated with ether drugs or alcohol. Many people turn to a whole different person when they are intoxicated. Some get mad easily and could literally kill someone for it and all because they had some drinks so they aren't thinking straight. Next thing you know you wake up and you are locked in a cell for life.

Killing another human being is not good a all. Many people do it for revenge, money, or simply because they don't like a certain someone. The worst part is that there are lots of people who have gotten away with it and have not been accountable for their actions.
