In Death something ends. The end. Gone. You may have wanted it to die, or not. You may have expected it or not. All that's certain is that it died. You morn for it, and, as said, it leaves a space for something new to take it's place.
This is important to remember about Death. It's not just about something ending, but your mourning for that end, coming to terms with it, and accepting whatever new thing takes its place.
Judgement is something that should have died, but didn't. That you kept alive, even if you thought you'd buried it. Either a wrong done to you or a wrong you did or some way you're living your life that's not good--etc. When you get Judgement, that's when you realize that it's time to lay it to rest. To end it and move on. This is something you want to to, and know should be done.
That's the important thing about Judgement. That you resurrect this thing, face it and come to terms with it, so that, at last, it can be let go. Which is why, rather than mourning it's passing, you feel released and free, and like you can start afresh.
