They probably do, but my guess is they still fear the pain.
If you think about the Crucible from a lore perspective all that repeated death within such a short amount of time seems kind of gnarly.
I guess folks can get used to anything if they experience it enough times.

He's also an EXO, so pain might not register the same for him. On the TV show Highlander (immortals), they never got used to it, damage is still damage, but they also know what types of extremes they could put themselves thru.
