I'm not going to visit my sick uncle
What is your reasoning for not visiting your sick uncle?
I hate that man, he is a violent drunk and an addict.
I'm sorry that your uncle is sick, but I also understand that there are past issues that you have a problem with. Those issues are valid.
I would rather see him die, I'm not going to waste my time.
It's your choice whether to visit him or not, but it seems that your feelings towards him are very negative and his illness doesn't change his past behavior. Violence and addiction can shape the lives of others and in this case it might be best to not visit and move forward.
