Crimson/History

Past
Crimson, through either inheriting or by creation, became the head of a major mafia criminal organization in hell. At some point in the past he married Moxxie's mother, and sired Moxxie, his only known offspring. Crimson's relationship with his wife and Moxxie was bleak, with Crimson unhappy with Moxxie's lack of commitment to his criminal lifestyle, and his wife's attempts to steer Moxxie away from said lifestyle.

It is hinted that Crimson ordered Moxxie's mother to be murdered. Crimson continued to force Moxxie to accept his criminal obligations, such as forcing him to execute imps and participate in violent skirmishes. He eventually elevated Moxxie as a fully fledged member of his mafia, prior to his arrest.

"Exes and Oohs"
Crimson's organization was facing financial troubles, because of this, Chazwick Thurman tricked Crimson into thinking that he was rich. Believing this, Crimson concocted a plan to forcibly marry Moxxie to Chaz so Chaz could become a fully fledged member of the family, and thus gain access to his funds. Crimson attempted to violently threaten and coerce Moxxie into cooperating, and attempted to have Millie and Blitzo executed when this failed.

After the failure of the marriage, and the discovery that Chaz had deceived him, Crimson seemingly had Chaz murdered, and would go on to mount Chaz's jaw and teeth as a pseudo-trophy in his home.

Crimson expressed great anger at his perceived betrayal of Moxxie towards himself, expressing his anger by throwing a dagger at an image of Moxxie.
