I thought about this story, and the attendant "Jason has issues with woman-abusers" message, when I read Battle for the Cowl 1 and saw that panel of the bodies hanging with "thief" "rapist" "murderer" signs on them. The obvious assumption was that Jason did the hangings, and based on this I could see him viewing rape as a hanging offense. (Given that his real mom turned out to be a thief at her charity, that too.)
They never do make it clear where that regard for women comes from, IIRC. Possibly it's just a personality quirk, 'can't abide rape,' with no story behind it. Jason does seem to like women in his semi-loutish way, viz. Donna, Holly and Harley, and relate to them with an ease that eludes Batman and to a certain extent Tim too, tho Tim has the excuse of adolescent awkwardness. Jason would hate to hear it said, but it's something he has in common with Dick!
