Wrestling is a scummy business. If it bothers you that much, just watch Being the Elite and NJPW except when Michael Elgin comes on.
You forgot about Ric Flair. Ric Flair has plenty of skeletons in his closet as well that every fan tends to overlook. Also Scott Hall and Kevin Nash.
To me there's no evidence of Ultimate Warrior being a monster. He definitely said some pretty awful things, but WWE also went after him with the 2005 DVD release and it was pretty much a hit piece that totally buried him.
What I will say is that Warrior should've apologized or made amends to the likes of Bobby Heenan and Droz. I'm disappointed he never did that before he died, but such is life. At the same time, Heenan went after him hard on the DVD, and I imagine that's why he said those things.
You can trash Ultimate Warrior for his verbal remarks, fine. But you can't sit here and tell me he wasn't one of the stop stars in the business in the late 80s and early 90s. And no he wasn't an in-ring technician, but how many top guys in WWE actually were at that point? So to trash him for that on his DVD was stupid.
I mean that character he created was a great character. He was crazy and his promos were crazy, but that's why they worked. Ultimate Warrior was like this wild unpredictable madman from like another dimension or outerspace. For that period of wrestling it worked, and the fans loved it. Meanwhile, now you have Roman Reigns and his THE GUY schtick that everyone hates.
Ultimate Warrior didn't want to be one of the boys. Boo ****ing hoo. Why does he have to be one of the boys? To be respected among a group of peers who are admittedly also scumbags in a scummy business? He didn't want to play their political games and kept to himself. He was friendlier with the staff and workers because he didn't want to be friends with the boys. God forbid he didn't join Shawn Michaels' Kliq to take control of WWE and show them the right way to run the show!
