But if part of your reasoning for not extending compassion/humane treatment to another creature is based on the degree to which it appears to extend compassion/humane treatment to other creatures... that would seem to imply we should extend less compassion to you vs. humans who extend more compassion to these same creatures, right?

I'm not suggesting that we treat you worse than other people, but rather suggest that this line of reasoning might need to be reconsidered.

That is, your rule seems to put you at a disadvantage if applied universally. Am I missing something?

It's against my base instincts, but the older I get, the more I try to extend compassion unconditionally. Among other things, I find it just makes me a calmer person. YMMV.
