You're both idiots with dumb arguments, now kiss.
Anyway this is a pretty neat manga so far, I can understand both sides here, the humans really can't trust demons and any misstep will be seen as an aggression, and Liese's nature makes it a bit difficult for her sometimes to control things properly, plus her past as an elite member of the demon army makes it difficult for any human to see beyond that. Makes sense to me.
Personally, as safe and kinda hands-offish as it may be for a plot twist, I think she never actually killed humans herself, but rumors about her spread because, again, elite general yadda yadda. Her undead spirits could easily be justified as being lost souls killed by other demons who were unable/unwilling to pass on because of spiteful feelings.
