It is crazy how depraved some men can be, unable to move on to other things and respect your space and boundaries, to the point that the only way to feel safe and live a relaxed life is them dying, unable to hurt and harass you anymore. It's a horrible situation, but it's not your fault for feeling relief that your psycho abuser is gone. I can only imagine the feeling, because I was stupid enough to give power to the wrong hands and now live in constant paranoia whether it will be used against me or not. Never give such power over you to any man, and don't ever reveal any sensitive information that you wouldn't want strangers to know. Most men can't be fully trusted, so there's no reason to risk it.
