Alex's Drama is getting old

I'm about tired of Alex. He was a jerk in the beginning, then he became halfway civil for a short, basically for the run of the show he's been flipping back and forth between being a good guy for a few shows, then he becomes a trouble making a-#hole for a couple of shows flying off the handle at whoever he's around. He suppose to be a doctor which means he should be smart enough to not make so much trouble for himself. Every-time you think he's starting to grow up, he does something super self destructive. It's maddening! In his latest incident, I believe jo deserves some of the Blame and I also think Deluca should of known better than to escort a very drunk Jo inside the house she shares with her boyfriend. At the very least, he should of not gone anywhere near her bed. But Alex is still the the who beat him senseless. I just am not sure if their is any redemption this time. To have a temper than can flare up like that is a serious problem and shouldn't be around children.This is one plot line I wish that would of passed on. Anyway. this is just my 2 cents.
