4) "They're children that really take it easy-" "Are you taking it easy for everyone's share? Marisa" "Yeah!! I think I'm being watched over by everyone!!"
Marisa is the root of this tragedy and by taking Alice home. Reimu is the perpetrator of the slaughter and by directing her babies action, Alice is complicit in refreshing w/ Marisa and coming to the house and, the babies action can't be fault with unless on technicality.

and that's more than enough for her to deserve a happy end
Marisa does not fess up her infidelity unless you count her action of 'dumping' Alice into the house then scram immediately w/o trying reconcile what happened.
What Marisa said was, 'If we take it easy together it will be fine'. Then she go out citing,'Family has grown so (she) have to get more food', then left.
So no, she still hasn't paid for her fault. If she deserved a happy end it is because she's alive. Dead people suffered.
