I think that Sam Egli, a pilot who helped recover Treadwell and Huguenard's remains, gives a pretty good analysis of Treadwell here (starts around 2:08):https://www.youtube.com/watch?v=kdkS3AYTGcg
I'll repeat what I said in another thread. Treadwell had no idea what he was doing. If Treadwell were truly aware of the risks then he would have taken the necessary precautions. These would include not getting so close to the bears, carrying bear spray and/or a gun, setting up a proper electric security fence around the campsite, and not staying in the park longer than he should have. Unlike Steve Irwin, who treated dangerous animals like they were dangerous and knew what he was doing, Treadwell (as Sam Egli so eloquently put it):>"[Treadwell acted] like he was working with people wearing bear costumes out there, instead of wild animals."
He took ludicrous risks, no real safety precautions, and refused to listen to the experts who gave him advice. I would be willing to give him some sympathy if it were not for several things. Firstly, he didn't just put himself at risk, he also got his girlfriend killed; she didn't even want to be there. Secondly, Treadwell was not a nice person. His rant against the Park Service makes this fairly clear. He would also harass people that came to and near the park while he was there.https://www.youtube.com/watch?v=gDQkLF1Vd3o>>1706775
Treadwell's antics actually caused several bears to be killed, so he failed to protect them. This isn't even getting into the fact that Treadwell's behavior would have habituated many of the bears, increasing the chances of human-bear conflict. Also, the Alaska Department of Fish and Game and the National Parks Service didn't need his 'help' to manage the bears.
