If you latch on to me and suck my blood, is it murder for me to remove you from my body just because you can't live without parasitically feeding off of me?
Re: bad for the creature, hyenas give birth through their clitoris. I'd suggest that's not great. Children cost an average of $233,000 to raise. That's certainly not great. That doesn't take into account career cost and opportunity cost of lost income. Sub-optimal too.
I'd describe children as mandatory lol.
