Try not to over complicate it for yourself this is why you are having a problem where a small child would simply say
Bad Bob - Poor Alice (victim)
Tell me again about how bob is A victim here and Alice is a blackmailer who deserves punishment. I like hearing you spout ludicrous nonsense. That is suchmoon like madness.
I'm not your mother. It's not my job to explain the "two wrongs don't make a right" concept in ways a small child can understand.
