I would find that very disappointing, we aren't obligated to become evil people because of who our families are and I think any writing that suggests otherwise is both lazy and sending out an unhealthy message and while Lena is capable of the sort of ruthlessness usually associated with Luthors she's also capable of the exact opposite.

And I strongly disagree with the "Luthors are all evil" bit, if you're just referring to the arrowverse versions then I don't think we have enough information on Lionel Luthor to consider him evil, infidelity alone just makes him a jerk. If we branch out to Smallville versions then you could consider Lionel evil for much of it, although he wasn't an evil man by the time he died even if good would be too strong a word and that shows version of Lena (Tess Mercer) had a ruthless side but was by no means an evil person. If you want to branch out even further then that then you could even find good versions of Lex like the one in the Injustice game.
