Sure, it's not clear cut, though at the point the notion of killing babies is seriously entertained the line has been crossed a long time ago, regardless of where exactly it was (and I don't even like babies!) And also, yeah, I doubt our views differ much in practice. And removing the alignment from humanoids would definitely be a big step in the right direction; it would solve the most obvious issues that have unfortunate real world implications, and that's most important. I still think alignment is a terrible system on its own right and should go for that reason, but that's just about game design preferences, and ultimately not a big deal.
