Bret is capable of being charming. Many psychopaths and others with personality disorders can be perfectly nice when the fancy takes them.
But watching Bret on the internet you are seeing the real guy, not some nasty alter ego that emerges when Mr Nice Guy sleeps.
Mr Nice Guy is a figment of Bret's overactive and occasionally productive imagination. The real deal is an absolutely potty-mouthed, spiteful, raging compulsive liar with a childish fixation that by wishing his enemies dead he can make it so. He's emotionally retarded.
