It isn't that anyone is worthy or unworthy of my respect, it's that some do things which make it impossible for me to trust them, much less think highly of them. I am incapable of truly respecting anyone who is duplicitous, insincere, constantly feigns victimization or refuses to take ownership of their actions / decisions.
Frankly, I'd rather keep company with a complete and unapologetic dick who knows they're a dick and owns it than someone who's surreptitiously catty and feigns ignorance to it.
But it has nothing to do with value as a being, I simply don't value you those attributes.
