It will suffice to point out that the purpose of a suicide mission does not make it any less what it is, a SUICIDE mission.

This is not how definitions work.

A word as applied in a phrase can mean entirely something else when used alone. If not, going by your logic it will mean that suicide doors (a term for an automobile door hinged at its rear rather than the front — Wikipedia) are doors made to kill one’s self.

When you have goofed (as you have obviously done here), it is best to look at your beliefs objectively and reevaluate them, rather than grasping at straws to enforce your point. Just my humble opinion.
