No, it doesn't frustrate me that people have a different experience than I do. If you want a mono SH you can have that. (and it's pretty easily

If do I have a frustration when RPGs devote lots of energy to evil paths *when that takes away for the main path*. Steam numbers tell us that 70-90 % of players go for the good path and I dislike what I see as waste of time that reduces my content.

But that doesn't apply here - I think I got my money's worth with BG3 even as I have some critiques. I got hundreds of hours and I never have to see the evil content.

Let me return your question to you - does it bother you that SH can kill the nightsong and pour her blood on the statue of Selune in attempt to deepen the grief of a mourning mother? If not, why does her capacity for evil offend you less than her capacity for ethical non monogamy?
