I doubt they are saying to discard all motives; specifically they said “murder is murder” so using cases that aren’t intentional (ie manslaughter, not murder) undermines your point. It’s more that there’s an upper limit or certain criteria where we stop caring what the person’s motives are, so where do we draw that line? I don’t pretend to know the answer, but it’s a question worth exploring even if you think you know the answer already.
