I'm thinking about not standing up for her.
Why aren't you going to do that?
I'm bothered not only by the fact that she is not worthy of any respect, but also that her intentions are often corrupt
If you're close to her, that's not cool. You should be there and stand up for a friend.
I would rather have her die.
That is mean of you to say. You should stand up for people who are weaker than you. They might not be grateful but I'm sure they will come to appreciate it later.
