Adele's version of the song could be thought of as being about a woman who kills her husband and says it's because her love of him made her insane. It is a cover, and the song was written by a man, so it was originally about a man killing his wife. However, this is done by a woman, and the pronouns have been changed to reflect that so in this version the wife kills the husband.
