Nobody can tell you what is right or wrong for you to think, feel or do.
If you really want to get your personal answer i suggest you to have an internal dialog asking certaing things and finding the answers on your own. Like a puzzle then youll know how to feel and how to better express what emotional impact his death brings to you. But whatever the answer is… be gentle to yourself.
For example, you can ask yourself:
Why would i like to celebrate his death? Really…
is it because no one else would be affected by his negative actions anymore? Or is it because he wont be able to enjoy life anymore? While ill do?
if its the 1st choice then embrace it and celebrate it if you like.
If its the second one then ask yourself:
- what if he wasnt happy living and dying was actually a strike of luck for him?
See how the dynamic of your internal “desire to feel joy” fades away if the answer is: oh… what if yes, what if he was miserable living and then dying would be like giving him a prize by freeing him.
Because no one, as terrible as they could seem to be are really happy. They are miserable internally and hate themselves deep down, thats why they cannot offer anything good.
…would the joy of his death stop right there and instead youd wish he would have stayed living a miserable life?
What if the reason why it makes you want to celebrate his death is an apparent punishment by losing his life?. A precious gift we have?.
In any case. Its your story, how you feel is how you feel and again no one can tell you what you must feel or do.
However you decide to feel, i hope it goes away so you can continue focusing on your healing and finding real happiness in your life.
Feel all you want to feel and then… let it go.
Come back to the present. To your life, because whether you celebrate his death or not, one thing is for sure, a long awaited to be closed chapter time in your life is here. And a feeling of a shadow always present in your life is not really there anymore in this dimension. Take advantage of that.
I hope it also leaves your mind and heart for good soon too.
