The first part was deep, the second part even deeper. I think Jericho explains it the best, Benoit wanted to have a legacy and with this act, he completely tarnished it. Something was wrong, either roid rage, CTE, PTSD (Eddie's death destroyed him) or anything else. It's still not justifying what he did, but it puts it in a more accepting perspective for anyone who worked with Benoit, watched his career or whatever.
Besides, it shows what great standup guys Chavo, Jericho and Dean are.
Nowinski as well by the way, for conducting the CTE scan and being worried about his former colleagues. I think Vice could've attributes more time to it.
Plus the interviews with Vince after the murder-suicide, I think they should've also shown the Mr Kennedy interview and then the week later him being caught with roids, showing that the wellness policy is still a fluke.
