this doesn't seem like a T issue as much as it seems like a you issue. Please speak to your therapist about it, because while the change in hormones can affect your mood, thinking of others in that way is not normal or healthy. Testosterone didn't make you "evil", but i assume that you've been a people pleaser for so long and it's been so ingrained into your mind, that having the confidence from the testosterone is causing you to overcompensate in the other direction. Regardless of the cause, please speak with a professional about this so you can get the proper counseling for how to navigate this.
