Killing hookers isn't doing it for me anymore

I suddenly developed the urge to kill Vanessa's roommate, Rachel.
I ran into an awkward situation with her last month, and although I gained the moral high ground, and came out as the intellectual victor...I know that I would simply feel a lot better if I was able to swing an axe onto her vagina, then at the open wound eat my way up to her stomach, tearing her flesh off with my teeth.
I am running into a great number of adversaries lately. Out of respect for the people I associate with whom associate with them, I've been heavily reluctant with my onupsmanship tactics. But sometimes I feel that even that won't be able to satisfy my emptiness inside. My anger is becoming more influential in my daily actions, and although I understand the politics of things should be better played to sustain sanity, sometimes I think I'd be much comfortable rolling in a pool of somebody's blood.

I can't play the game unless I know there is someone who poses a great risk to me, the thrill of getting caught is the only motivation for the pretense. I need a fucking challenge.
This new testosterone booster I've started taking isn't helping my problems.
