@NoSoup First you shouldnt forget that these people there have other values and she is living long enough there to adapt to it quite a bit. Second is that she most likely doesnt actively sees it(she is focused at Alejandro and Lily since the fight started ... the human brain is incredible what it can blend out and instead lets you focus on something else. Lastly we didnt saw anyone begging for their life while dying or even crying and so on, therefore saying she enjoys that it quite a free way to interpret any of that.
If you live in such a world such a thing is something you need to accept and to stomach, otherwise you will get killed or even worse.
Honestly it sounds more like you condemning her and making her something she clearly isnt. It sounds like SJW stuff without realizing the art of world she is in and so on.
If people who cant understand things and people who dont think about it in the first place, could just stay silent.
