Do you think its normal for me to be bothered by my oldest brothers existence, given all hes done?

To say that he's been horrible to us would be the biggest understatement ever, in short he's used, abused, manipulated, and robbed us blind for nearly 14 years. Last time he was around I was so infuriated I was ready to stab him, but instead I sprained my hand punching his face (it was a while ago though, my hand is all healed, and it was well worth it). So then we kicked him out and he kept calling me (probably to harass my mom for money as he did when my mom was working before), and he had me so angry I told him to kill himself (that was also a while ago), and then I discovered he's posting stuff online, and trying to make us be ashamed when we've given him so many chances (he must have had thousands). I find it so bad that he has no shame and he's trying to make us feel ashamed. He has no idea how badly im broken because of him and my dad (whom is very negative, and yells at you for everything, and that's why my mom and him got divorced); I've been having mental issues (depression, anxiety, mood swings, cutting) for over a year, and im sure if he did know he wouldn't care. Even now when hes long gone i wish he were dead. Do you think how I feel is normal given all that's he's done?
