Benny had been in Purgatory for decades (50 years, if memory serves). Purgatory has been described as worse than Hell. A bad sunburn doesn't compare to either of them.

As for the most recent episode, just because he didn't show any discomfort doesn't mean it wasn't there. He could've been hiding it to... y'know, trick Alex.
