Is it wrong to hate my cousins who get to see my brothers every single day?
Why does that make you hate your cousins?
I think my cousins can be so terrible towards my brothers.
Are you sure that you hate your cousins or are you jealous that your cousins get to see them every single day? You should be happy that they get to spend time with one another and hating family members is always a dangerous path to go down. Being supportive of them would make you feel a lot better, I think.
I don't need your judgement. My cousins act like jerks to them.
You cousins sound like jerks and if you want to protect your brother, then let your parents know how they are being treated.
