Is there anyone who enjoys being a Dreadnought?

I always hear about how it's a living hell for those entombed, but surely there's some ultra-fanatics (in the Imperium or Chaos) that really enjoy the experience?

Be it a better opportunity to smite their enemies, or with Chaos, just some general perverse personality that gets off on the suffering or increased slaughter?

Surely Custodes aren't too bothered by it? Being they only live to serve the Emperor after all.
