I was thinking the same thing the other day. I have a friend that had a pretty rough childhood and gets away with everything short of murder because the people around him treat him with kid gloves. He's the most entitled person I have ever met. When he doesn't get his way he has a little tantrum and he's 38 years old. There comes a day in life when you come to terms with your lot in life and get on with it. Especially, after 18 years of seeing a therapist. Seriously, life is for living. It's time to live life.

Absolutely agree. Accountability is for all of us, not just those very few who were lucky enough to have had a perfect childhood!

Once I was telling a therapist who had worked in the prison system about my childhood, and they started crying! (Actually, pretty disconcerting.) However, I consider myself a self-made person, and how I know I'm successful is that I am surrounded by lots of people who love and support me. It's knowing what is right and wrong, and consistently making the right choices. If you grow up in dysfunction, it serves you well in life to cling to honesty and the truth in all things.

There's way too many people in the world that use their pasts to justify shitty behaviour. I put up with an extraordinary amount of abuse from "friends"/family until I realized: "You know what? This is bullshit. I don't treat people like this despite what's happened to me. What's your excuse?"

Thank you, OP. Nailed it.

There's something to be said for compassion. Your wording is a bit careless: "just because" and "rough childhood" imply zero understanding. I agree that abuse is wrong, but you can't just wave your hand at someone for having a "rough childhood" as you put it. Trauma at a young age, especially ongoing trauma, will break a person and create unhealthy coping skills, and the absence of emotional skills that other people aren't missing... If you care at all about helping people and dispelling mental health stigma, you may want to reframe how you speak and think about people's behaviour. Kindness, educating yourself, and understanding can change a sick person's life for the better; it can help them learn how to NOT be abusive, how to get help, and how to break free from what's happened to them.

blah blah blah

Obviously you are assuming that the Op has no compassion, but that’s not a fair assessment. Sure we all know people who have had a very bad time of it, and yes we also understand that they are behind the 8 ball when it comes to learning how to cope with life and other people. What we’re saying is that simply because it’s harder doesn’t mean that you get a pass and can be a jerk for the rest of your life. Just like being an accident victim who winds up paralyzed, or being the victim of an awful disease also doesn’t give you a pass to take out your pain and rage on the people around you. Each of us must learn how to cope with our individual challenges in such a way that we don’t punish the people around us because of something that they aren’t responsible for.

I agree with the op. Most people have had a shitty childhood and most of them work past it and move on. I had a terrible childhood which included sexual, verbal and physical abuse. Most of my friends also had at least one of those three or more, and we were the lucky ones.
Imagine what it was like over the last 1000 years and before, life was rough, but here we are living in the best time, in the best country in the world and making excuses why we are so hurt by life.
