What do you think about me always considering murdering my uncle?
Why are you thinking about murdering him?
Because I will never be able to trust him.
Personality conflicts and disagreements with family are one thing. But, thinking about murdering someone is taking that to a scary level. Have you considered talking to someone professional?
It's only hurt feelings bs, I wish he would get cancer.
Wanting someone to die is wrong. It's best to consider ways that you might be able to forgive you uncle. If you can't it's best to keep your distance from him.
