By my morals, intentionally causing one or more deaths or knowingly taking actions that might lead to the death of a human is simply not allowed.

Under no circumstances is it right to knowningly cause someone to die. If someone does cause someone to die, intentionally or unintentionally, it just is wrong no matter what.

There is no such thing as "needing" to kill someone, or a justified death. It is the responsibilty of everyone involved to prevent that any such situation occurs, and if such a situation occurs, to resolve it without the need for any death.

I have more important details and clarifications coming soon.
