This also explains why he says Sokolov is boring. His choices seem to always be 'the ends justify the means', the ends being scientific knowledge with no further goal beyond that and the means being anything he feels like, regardless of morality. His choices, therefore, have no personal meaning, he could never make a choice that would compromise who he is because there is nothing to compromise. He will never be able to make a decision that would haunt him because he either has no conscience or he's very good at rationalizing.

Piero actually seems to have some scruples (indicated by the note he leaves in your room if you dealt with the weepers in the sewer non-lethally) therefore his choices have a deeper meaning to him personally, as evidenced in his dialogue when you catch him spying on Callista taking a bath, where he expresses both guilt and disgust with himself.
