Sociopathic or generally deranged love interests who we accept as they are—mostly because there is no changing them.

This list is for our morally grey (or not grey and just straight up awful) characters who aren't secretly actually doing everything for completely redemptive reasons. Trying to keep the scope to stories with romance/spice elements rather than straight spicy books—mostly because it's not difficult to find dark romance with dark characters.

Suggestions to grow the list welcome!
