Then go ahead and figure out how “I don’t like seeing living beings suffer” is consistent with the idea that a moral compass is wholly “internalised”. Are you saying that your dislike of seeing suffering is “internalized”?
I’m exactly pointing out that how you feel about about harming and hurting others will be part of defining your moral compass (quite literally by leading you away from harming and hurting others because doing otherwise makes you feel bad).
Yeah, absolutelly, a lot of “Moral” is internalized, but a lot of it is just outsiders trying to claim as their invention that which is already human nature and the natural compass we have due to things like love and empathy.
Consider the possibility that societal Morality is really just a way to capture and subvert natural human “morality” (which is not at all a formal “Moral”) so as to get people to act outside that natural moral (for example, would Capitalism exist if people just followed a natural tendency to stop hurt when they see it and take from those who have much to give to those they see starving?).
