See what she does to me? My loving wife...
~ Robert Baratheon sarcastically talks about his marriage to Cersei Lannister.
Villains who are or were married, be it to another villain or someone else.

This is not automatically inclusive with In Love villains, as some marriages are unhappy, especially when evil people are involved. In some works, it is presented as a given from the start that a villain is married, even if they clearly do not love their spouse and there is no apparent logical reason why they should be together.

In some cases, it is possible for marriages to be very strong and for the couple to genuinely love and be faithful to each other, even if either one of the spouses is evil or both of them are. Some of these couples can be redeemed.
