The question as to if I can kill someone to save another person is a very difficult question to answer. This is a very complex question, not the kind of question that has a simple yes or no answer.
Taking a human life is something I never wish to imagine doing, but some times, life can places people in situations they never planned for.
Personally, I see myself as someone who cannot kill a fly talk more of killing a human being. Under normal circumstances, I would never choose to take another person's life to save someone else. Life is precious, and once it is taken, it can never be restored. Living with such a decision would not be easy, and the weight of taking someone's life could follow a person for a lifetime. So in a normal situation, my answer would be no, I can't take any body's life to save another person.
However, life can place you in a difficult situation. Sometimes, things happen very fast, and decisions must be made in seconds. In such moments, you may not have the luxury of sitting down to think about morals or consequences. Your actions is based on instinct, fear, and the need to protect life. Why do I say so?
There are some decisions in life that must be made instantly, in some moments where decisions must be taken instantly, doing nothing might sometimes lead to the loss of life.
Imagine a situation where a terrorist, bandit, or assassin is holding an innocent person hostage. The hostage is being beaten, tortured, or threatened with death. The attacker has already made it clear that they intend to kill the innocent person. You are standing there, and somehow, you have the chance to stop it. Not by talking, not by negotiating, but by acting immediately. In that moment, doing nothing would almost certainly lead to the death of the innocent person.
In such a case, I believe I would act, I will kill terrorists because allowing an innocent person to die when I had the power to stop it would live me with guilt. Choosing not to act would be a decision, and that decision would result in the loss of a life that did not deserve to be taken.
I've had personal experience with terrorists group. Terrorists are very heartless human beings and show no mercy when they want to kill someone. I say this base on what I have seen and witnessed. There was a time when my parents were still living in Maiduguri, in Borno State, in the northern part of the country (Nigeria), where terrorist activities were more pronounced. During that period, the community where we lived experienced an attacks from those terrorists group. (Boko haram).
On one of those days, terrorists invaded the community and opened fire on people. Everyone ran in different directions, confused and afraid. My family and I narrowly escaped death and we were forced to hide ourselves and sleep in the bush that night. When we returned the next morning, the community was looking like a war zone. Bodies of many people were lying on the ground.
Because of experiences like this, the question feels very real to me. So when I imagine a terrorist or any body with weapon that could kill a person, holding someone hostage, and ready to use that weapon on an innocent person, If I had the opportunity to stop such a person and save an innocent life, even if it meant killing the terrorist, or the person that is having weapon, I would act. Not out of anger or hatred, but out of the need to prevent another innocent life from being taken.
That does not mean I believe killing is the right thing to do in every situation. The context of the situation matters. There is a clear difference between acting to protect a life in immediate danger and taking a life out of revenge or personal interest. If there is another way to stop the situation without killing, that option should always come first.
So the question of if I can take a person life to save another person depend on the context of the situation. On normal situations I won't take any body's life but in situation where I need to act fast and make a decision to save someone from be killed by a wicked terrorists or someone who is having weapon that is ready to kill an innocent person immediately, I will act and kill that person if I could.
That is what I believe.
