If a person wants to have a war and another person wants peace, how can they coexist?

This is an example, another could be if someone wants to kill a person and another wants to save that person from being killed, can they live in harmony?

To put my 2 cents on my own question: it’s impossible. From this, I gather that society wants to trade security, that is, have omnipresent or something police force that mantain stability in the society, for freedom, that is, big brother is watching you. And, now that I think about it, that’s the answer: the only way to avoid conflict and have opposing views of love/war, life/death at the same time, is the lack of privacy. Being accountable at all times whatever you do. Only then can we learn to be more responsible. Otherwise, wars will continue to exist.
