Is this a stretch?

I was sitting thinking about my essay and I realized how bored I was with the topic already and how I had barely started writing. I then started thinking about other people, in the real world and in fiction, and how the ones with power tend to have some tragic back story (i.e. batman) or just be generally empty. I can easily prove that Maxim after taking rebeccas power (that's the angle Im going to take)became very empty and sad. I need some helping supporting the Rebecca part. The only concrete evidence I have is when she got maxim to kill her, almost as a transfer of sadness! But I want to be able to say something to the extent of her having all those affairs to fill a void in her heart. does anybody have any evidence that might help with this?
