Should I list every major conflict, real and fictional, in which despite full understanding of the imminence of war and a long history of hostility one side was totally unprepared and got rolled over? I won't twist your words into something outlandish and incriminating, like for example you condoning torture if it's committed by 'the underdog' of a conflict. In return, can you please do the same in the future?
I only said that I'm okay with people's awkward and direct attempts at courting, and with them getting frustrated by the failure. Never said that Lieve kissing you after you expressly stated that you aren't interested was okay. However her actions can't be equated with using date rape drugs even if we assume that she does apply the Venom, which game doesn't not recognize. If anything, it's akin to dumping a bunch of fantastic aphrodisiacs (since RL ones won't work that fast or mix with the alcohol) into a drink of your failed date and leaving them confused and aroused. Not something you should do but nowhere near being criminal offence.
It will probably come as a surprise for you, but we have no evidence suggesting that Sierva is addicted, because she doesn't display any of the symptoms (she is anything but dopey) and we know that without exceeding a certain threshold repeated dosages of RMV can be taken and without addiction forming. Mayren surely is addicted to venom but it may just be the result of her unusually strong reaction to it. Speaking of Mayren, Lieve mostly reacted in a way you mentioned to the most airheaded and bimbo-y of her remarks, but even then it never got degrading or dehumanizing.
Now for the main point of contention you have: Lieve deciding not to suppress her venom production and using it on her trench wives.
It can be attributed to her fully embracing the positive view of venom and even the possibility of ab addiction, although to substantiate that we'll need
@Savin to chime in and tell us if Lieve would have been okay with getting venomed by PC or someone else, or if she is a hypocrite.
