I helped to undermine her job, her life, her sanity
I don't like what you did. Did she get back to you about it?
I know, it's not a good thing to do...
If you know it was wrong, why did you keep sabotaging her and destroying her whole life and job? That is just plain sadistic to continually make someone's life hell and you need to take a look into the mirror.
I just wanted to help the company out by ruining her.
Do you really believe that the company will care about you if this is how they treat others? You should want to show compassion and not try ruining other people's lives just because a soulless company wants you to.
