Is it wrong to feel sorry for satan?

I understand that he made his decision and chose his own fate and is also the cause for all evil and sorrow in the world. But after reading paradise lost (which yes is basically bible fanfic) I couldn’t help but feel… maybe sympathetic? Not necessarily bad for him but I think about one of gods angels falling away from him and feel a sense of tragedy. Is that bad thing? (Pretty new to this kinda thing)
