They weren't ready to give up on that heel turn. They did everything in their power to have people boo Austin. The Two Man Power Trip was the best thing going. People were ready to cheer HHH so the inevitable feud between him and Austin would have kept the heel turn alive. When HHH got injured they couldn't use the Power Trip to build anymore heat for Austin so they tried the next thing; turn him into a goofy comedy heel with Kurt Angle. It didn't take as well, people liked the comedy and they started cheering them. Worse still, they made Austin and Angle antagonists against the invading WCW and the crowd wasn't having it. So then they were like hey, they hate WCW, let's throw Austin in there.

So Austin went from goofy/crazy heel back to his Two Man Power Trip persona with a little crazy thrown in but the whole Alliance was looked at as so inept Austin was pretty much an island on to himself where whatever heel heat the group was building wasn't reaching him. Finally they gave up and turned him face by sacrificing Angle's heat. Angle was a mole for the WWE and ended the Alliance but somehow became the heel?

A lot of heat was killed with that Invasion Angle. The Dudleys and Kurt suffered the most. Thinking back on it HHH getting injured fukked up a lot of shyt. That Austin/HHH feud could have carried them into 2002 and they could have started the real invasion with the NWO.
