Sure, but if that were the case, then 98% of the workers in the game might as well have "positive influence" then, which wouldn't be correct. What you said is exactly true, they show up and do their job with little complaint, which to me is a 'Normal Wrestler' setting, neither negative nor 100% positive. Only people I listed as true negative influences were ADR and Sin Cara, who have been in numerous backstage fights in the recent months.
I was mainly speaking for in-game, as for my current TNA game where I hired him back, he is literally showing up drunk or hungover at 3 out of the 4 shows I run a month, lol. Doesn't feel that'd fit true to life these days. Recent interviews and an AMA, if we are going off interviews, he's cleaned up recently. Whether you believe it or not I guess is the thing. And I don't feel WWE would be taking him back if he was still truly messed up. Regardless, painkillers are the biggest thing that were destroying him, and in the data he had 0% in his painkiller slider.
As I said though, these are all just suggestions, just thought I'd chime in since I had no idea the last time the personalities were possibly touched.
