Well, DPC never named CHICK to be all good and DIK to be all bad.
There is no such thing as absolute good and bad.
Being gentle doesn't mean to be feeble and being rude doesn't mean to be strong. That's just behavior difference and from my experience I may say sometimes it's more paying to appear "CHICK", sometimes "DIK".
in my opinion the paradox remains, it is not a question of strength, but of "fame"
an MC CHICK is worthy of trust (even without real reasons) but can betray it without remorse (and for now without consequences, an MC CHICK can arrive at the end of the 7th chapter in relationship with all 5 LIs...). is it not a contradiction in itself that someone considered universally trustworthy is the only one who can completely betray it?
an MC DIK is not trustworthy (even if he had real merits) and is normally dismissed with remorse of the LIs (and can end chapter 7 with 2 LIs plus some hope..., provided he resisted Cathe's temptation, from which an MC CHICK is normally completely exempt, having the possibility to continue with Maya and Josy)
basically affinity is a 100% external matter to the MC, it doesn't concern who he is but only how he is perceived, without merits or demerits.
