It's the stark contrast between her acting cute in everyday situations, plus Anya admiring her, when during her "job" she's massmurdering people without second thought. And again, as of episode 2 it doesn't seem like she's murdering only evil people. And that, yes, is a moral issue for me. Frankly, I would have a problem with a character murdering evil people with joy, too. Murdering people just isn't fun, cool nor cute. Unforuntately, too many entertainment media portray it that way. As I said, this isn't a Spy X Family-exclusive problem. I remember having huge issues with that during playing Fire Emblem: Three Houses for Switch. "Oh, I'm cute Bernadetta, locking myself in my room all day ... except when I'm on the battlefield, then I murder countless people with my bow and arrow". Fuck off, Bernie. :/ I hate these dual-personality characters.
