Not fair to visi

After getting the hero ending with visi, romancing BB, and sparing shroud, I started looking up the other endings and noticed something not really fair to visi? When we make Robert kill shroud we get a short suspension and that's it, a slap on the wrist for punching his face in and strangling him. Very brutal death! Now if you didn't inspire visi to be a hero, she kills shroud herself, a quick knife in the throat and a little shit talking. But for some reason this makes visi a villain? She literally just saved Roberts life by taking out shroud and did it in a quick and clean way. I feel like if visi would have just stuck around after merc'ing shroud, she would still be a hero. The z team would accept her because she saved the day and stopped shroud. BB would probably suspend her but I doubt for very long. Maybe if there were another ending in the middle ground, where she kills shroud but sticks around. You could have Robert give her a little talk like, heros don't usually kill, but at least you're on the right side. A sort of halfway hero ending. I guess I just don't understand why she is automatically labeled a villain for doing what a lot of players made Robert do. What do you all think?
