Is it normal to feel angry when a loved one dies?

Try punching random pedestrians.

When my mom died I felt things I never would have predicted or saw coming. It's normal. I was mad at the condition of being human, knowing that sooner or later everything and everyone that is most dear to you is going to be ripped away and there's not a damn thing you can do about it. Somehow, you just gotta roll with it. So I started doing mundane shit to keep me mentally grounded. Like cleaning the toilet, lawn work, just to give me other things to think about.

Write a letter to your Grandma telling her all the things you didn't get a chance to say. Don't hold back, let it all out and you will feel much better.

Its normal.

yeah we can feel guilty or responsible for the deaths of others despite not having anything to do with a death, kinda sucky, but smashing things up with a baseball bat/ helps

Anger is a normal part of the grieving process.

Not a lot of anger from someone dying... but I suppose it's due to them dying of a ripe old age, or self inflicted ailments such as lung cancer after smoking after fifty years. My grandfather went out like a badass "aw fuck it, dont put me on chemo just pump me full of morphine until God calls". That's the kind of attitude I want to go out on.

Totally normal: that's why family members get into stupid fights over Auntie Flo's old vase or Grandpa's tools. I saw this a lot when I worked in legal offices, but have also seen it in my own life and in my own family.

A friend warned me about "misdirected rage" when I was supporting someone who'd had a lover and then her son die in a short space of time, and sure enough, that's what was directed at me.

I thought I was the only one who felt this way when my grandparents passed. so I guess is normal.
