I hacked my uncle accidentally.
What was your reasoning for hacking your uncle?
I hacked him as punishment for not loving me as much as his son.
It's unethical to hack into anyone's personal data and doing so might cause you to get into legal trouble. You should instead sit down with your uncle and make amends with each other rather than resorting to revenge.
He is too big for his own britches, he deserves to be grounded.
I understand that your relationship with your uncle is strained, but it's not your job to punish him and invading his privacy is wrong and unhelpful. You should talk to your uncle and let him know how you feel, as having a dialogue will help start the process of mending your relationship.
