I know he was brought in and pretty much just made the top name of WCW from day one, despite having 0 wrestling experience ever : p I bet that made the other guys in WCW look down on him a bit, which made him bitter about the job.
Though he was super popular in the company, despite Nash claiming that they planted people in the audience to chant his name, everyone in the audience did it anyway, and still do to this day, meaning they liked him : p If I gathered a group of friends and organized a chant for someone like Glacier, I really doubt everyone else would join in : p
EDIT: So Id have to imagine he had some passion : p But no idea, I barely no the guy. Though I do believe that he took his character seriously, and probly didnt like the idea of not being the top guy in WWE (his entire gimmick was the unstoppable machine)
