I don't think it's empathy cause' he wouldn't have done all the degrading things he's done to bottom if not. It's more a feeling of fascination (bc bottom is strong, persistant...) added to attraction (he's clearly attracted to him since first day), resignation (he has no choice but to let mc live, since mc is determined to sacrifice himself for the organisation, so he processes to give him medical cares even though he's the one hurting mc...).
But yes, he does feel bad for Benjamin.
Don't know why I'm still here, I must be really bored, lol...
