Thanks heaps for many ideas I think everything said here makes sense, and I will not argue with any of them because they are all right in a way.

just to stir up more discussion. Say if theres a family who hates your family. Who could be coming to kill you any moment. Why are we not allowed to kill them in order to live in peace?

Ill keep observing the arguments, and hopefully I can come up with my own ideas soon.
