> Why is it wrong to murder conscious things but not unconscious ones?

This is a bit pedantic isnt it? I would hope you can come to a conclusion which isnt borderline psychopathic

Yes, suffering is an unavoidable part of life which most organisms seek to reduce as much as possible. Given we all have existence bias and presumably dont want to end our lives prematurely, why would you knowingly want to increase it for others? I should have taken the hint from your initial response of "why is killing animals bad" that this would have been a pointless discussion. Why is killing anything bad?
