be (not) (one's) brother's keeper

To be responsible for another person's actions. This phrase is often used in the negative and can refer to anyone (not just one's literal brother). Of course I'm disappointed that Travis got arrested again, but I'm not my brother's keeper. When I'm babysitting him, I'm my brother's keeper.
