If you built good systems that have reliable backups or rollback mechanisms, dev should be able to have a beer on a friday and do a deployment without worrying about the fire they just caused. I'd rather a culture where people admit to their mistakes than one where they try hide or get whipped for owning up to them. We're people after all and some of us like a glass of wine and unwind while still performing our duties as engineers. After all, it's not like we're in charge of life support or critical systems which absolutely cannot fail.
