Is it normal to want your ex to die?

If you're comfortable with her being dead, then you also should be comfortable just forgetting about her and moving on.

so you didn't do anything in this relationship? except stand there and LET her screw you over. you're not mad at her, you're mad at yourself for being such a putz! you let your johnson do all your thinking pal, and it's dumber than a sack of wet diapers.

That’s taking it a little far, don’t you think?  I’d recommend not dwelling on her situation and concentrate on your own.  You’ll be a lot happier and eventually you’ll forget about her.

No, it's not normal. Get therapy perhaps to deal with your anger issues / help you move on.

Welcome to the real world, women move on extremely fast because they don't invest their emotions the same way men do, plus they got way more options. She was probably talking to him while you two were still together if she moved on that fast. And no it's not normal to want someone to die for something so trivial. Take your ego out of the equation. You're not that important as if you're too good to be hurt by a woman. It's not that serious, women do this all the time to guys. Women don't have the ability to love you the way you want to be loved as a man (Women only love their children), it will never happen so make your own happiness and understand that other people always have the ability to hurt you, so when you start investing your emotions you lose. That doesn't mean you can't enjoy a woman's company or have a girlfriend, but understand that them hurting you is out of your control so don't invest too much in them emotionally to a point where you believe she would never hurt you. When a woman hurts you,  you should be able to laugh and walk away from her permanently. That's a true alpha mindset. No whining, no complaining, no crying over a woman, just straight up walking away like it doesn't even bother you. Hell, she might even come running back to you if she sees you have the resolve to walk away from her without a second thought. 

Your best revenge isn't about her suffering. It's about you NOT suffering. I suggest you stop wallowing in misery. I'm not saying to forgive, to forget, to let go of your anger, to be OK with having been wronged. Only saying that dwelling on it, nurturing the negativity, is hurting YOU -- not her. Stop dwelling on it. Moving on, being better off without her, having a good life and never thinking of your ex is the best possible revenge.
