You escalated your example a bit fast (putting it squarely in the territory of a maybe overly emotional argument), but you touch on a not unreasonable question. Does the horse's right to decide who it has sex with not factor into this decision at all?

In an amusing twist of fate the horse would probably not exist had it not been for a long line of humans deciding which horses bred with which other horses to produce the breeds we know today.

i'm sorry i escalated? the person i was responding to cited the distinction between murder and manslaughter?

>I'm saying that intent informs morality. eg: Murder and Man Slaughter.
