look all we know is that Lucic has multiple public instances where he has been violent, or near-violent and all of them have apparently involved alcohol. It's not like it's some stretch to guess that he's got a drinking problem. alcoholism isn't just about being addicted to alcohol, it's also about allowing alcohol to be a catalyst for bad behavior. Even if Looch only drinks occasionally, but can't control himself when under the influence then that's a problem.
anyway we don't know all the facts, but it's common sense to say that the guy who just got arrested for attacking his wife while drunk should probably quit drinking altogether if he wants any chance at repairing his relationships with his loved ones.
As for the comments about Monty, I may have been generous in my interpretation of what people were saying here, but I didn't take any of the Monty mentions as people saying the situations are the same. Just that Monty has been through an experience where he let his demons hurt himself & people around him and managed to get right and redeem himself.
IF Lucic avoids jail time and IF his family is willing to give him another chance, then that almost certainly involves ditching alcohol, making amends, etc. and in that case having a guy like Monty to lean on would be a blessing. I don't think making that observation implies that the situations are exactly the same or that it's a foregone conclusion that Lucic can be redeemed like Monty. Certainly there are certain lines that if crossed would change the equation entirely.
