Eddie Guerrero

From Figure 4 Weekly

A well liked guy who overcome many personal demons to become a great worker and on air character.

Even after his death he was a major star on WWE TV and headlined Wrestlemania.

His death lead the WWE to implement the WWE Talent Wellness Program in an attempt to stop tragedies like this happening again. Apparently as soon as the grief wore off, so did the legitimacy of the program.
