he died and i didn’t cry

so my grandpa passed away recently and I feel guilty because I didn’t cry. I was never really that close to him and every time I was around him he said something ignorant and rude to/behind someone’s back... I know he didn’t treat my mother good as a child and he also physically abused my grandmother. of course I don’t believe anyone deserves to die and he is no exception to that. I just grieve for the life he could’ve had if he were kinder and how much more beautiful the world could’ve been to him if he had looked at things in a more loving and gentle way. I just feel guilty that I didn’t cry and that I’m going about daily life as normal... am I a bad person??? he’s been sick for a while - we all knew it was going to happen soon.
