If you're a vegetarian, you kill plants and eat them.
What does that make a humanitarian?
I can argue (with a straight face) that when I eat pork and carry a pigskin wallet, I am giving that pig a chance to participate in the human spiritual experience a little sooner than it would have otherwise. It wasn't going to live forever, no matter what -- neither am I.
I recognize both of those truths, and I am grateful as I make its meat part of myself, and cherish its memory in the feel of its skin, having chosen it to protect the sacred items that define my place in society, my identity and livelihood.
Religions have been based on less.
