I feel partly to blame for my brother being in prison for life
Why do you feel to blame about your brother being in prison for life?
I convinced him to rob a bank a little over a year ago and he got caught red-handed.
You gave your brother terrible advice. Feeling guilty is understandable, you should try and support him.
I will try but he will be spending 40 years in prison, so it's not like he has a good time ahead of him. My life will be just fine because my parents are going to take care of me and I wont be in jail.
You own him an apology and your support.   Although he made the choice you were a part of that.   To be that non chalant is not a healthy think to do.
