'You' Season 2: The rise of Love as a sociopath as she inadvertently follows trails of Joe Goldberg from Season 1
Love is one of the protagonists in this series, who thankfully did not succumb to a fate like Beck. So far she has actually helped Joe transform into a better person. It's clear because Joe hasn't exactly killed anybody in this season, except for Henderson, which can be deemed as accidental death, maybe.
When we first get to see Love on-screen, she gives off a very eerie vibe and something about her isn't right. She's a great person when it comes to her profession, but as a person, she is broken and torn apart. First of all, she is a widow and she freshly got out of a major traumatic experience in which she loses her husband James.
She was heavily in love with him and when he got sick, she could not save him. Although she tried to do everything she could to keep him with her forever, she succeeded to an extent because she still has him preserved in her memories.
All this while we kept thinking that it was Joe who stalked Love and flew down to LA, but in fact, it was Love who lured him from the very beginning. She knew that he had been following her around even in Anavrin, where they first meet.
She quickly becomes infatuated with Joe and imprints on him. Once Joe and her get close, her desire to be with him increases only to become more obsessed with him. There was a point in time where she gets into Joe's house at the time Candice was planning her move to find proof about Joe. She is always three steps ahead of the target. It is something Joe would usually do.
There's a whole new crazy in Love's eyes and it becomes more intense when she looks at Joe. Sometimes, it even feels like she could be mentally unstable and delusional. She is literally a female version of Joe in this season.
Love is territorial about her one true love and in the past, she lost James, and this time she can go to any extent to keep her present "one" safe and with her forever. All she was seeking for is love and acceptance from Joe.
In the past, we learn that the au pair, Sophie gets murdered by Love because she was trying to rape Forty. Her intentions were to protect her brother, but in that chaos, she makes it look like Forty did it. Being broken has really made Love into this person she really isn't. She gets so desperate to keep Joe in her life that she ends up killing Candice and Delilah because they almost got into her way of having a happily ever after that she was looking forward to.
She is not exactly a cold-hearted person, but her traumatic experiences turned her into a monster, just like Joe.
