between P&P and VoW.

Wronged woman:
Olivia - seduced by a man she KNEW was a rake
Lydia - seduced by a man who deceived her

Olivia - seduced then abandoned
Lydia - seduced then married (no opportunity to be abandoned)

Olivia - penitent
Lydia - blissful

True, Olivia's abandonment did bring about her penitence, but I don't think that if Lydia HAD been abandoned she would have been penitent. She would have just blamed whomever Wickham ran off with next for 'stealing' Wickham from her (a la Mary King).

Wronged father:
Primrose - forgiving, accepting, charitable
Bennett - unforgiving, rejecting, resigned

Here I think the fact that the wronged woman was either penitent or not plays a BIG factor in the father's reaction.

Clergyman:
Primrose - truly 'Christian', understanding, forgiving, discreet
Collins - un-Christian, judgemental, unforgiving, indiscreet

Here I think the character's inherent morality decides the reaction, not any perception of taint by association.
