It would be easier if my brother died instead

My father passed away a couple months ago .leaving me with an ingrat of brother. He’s 24 no job has a baby ,pays no rent . My mother enables him by giving him money every week , therefore reinforcing this idea that money falls from the sky. I hate him I really do . He’s mean aggressive and I think bipolar. I do fear that he will hurt me someday. Sucks cause I know I’d have to leave the house I adore. My dad was the only one that can calm him down. He’s a shit brother really . When my dad was sick I took care of him , I had to beg my brother for help. Dad passed I held down the house made sure bills were paid.And I’m still holding it down. My brother is a good for nothing piece of shit. I hate him
