Legally speaking, is murder stealing?
(And yes, "legally" matters, because we're talking about laws in this thread, not colloquial "their life was stolen" type expressions.)
This question is obviously (hopefully) rhetorical, no need to answer. My point is that different crimes are different. Otherwise literally every crime is stealing, and no other words for different crimes matter. Obviously different crimes are different.
