There's a baseline of respect people get for being human, they have wants, needs, beliefs, belong to cultures, they get hungry, feel pain, don't want to needlessly suffer or die, etc and those aspects are universal.

I'd use the word humanity to describe that level of respect, to contrast it with something more or less universally regarded as the lack of humanity, things we might even consider crimes against humanity, where people are deprived of the respect towards their humanity, denying them food, inflicting pain, eradication of culture, systematic murder, etc.

Obviously there's a lot of gray room between the two where, for example, cruelty for the sake of cruelty, in most circumstances, could be considered a lack of respect that people deserve for solely existing. That's certainly not on the level of crimes against humanity, but I wouldn't say that's respectful, either.
