Good people sometimes do very stupid things. I'm a great example.
I came from a family of very modest means. I had an amazing run of luck at a very early age (kind of like hitting a contract in the NFL to a lesser degree) and I acted irresponsibly.
Whatever you are thinking of right now, I probably did it. Short of hard drugs, I went wild. I partied hard, went through women like Kleenex and finally ended up with 3 DUIs. Fortunately none of those ended up in accidents, or in anyone getting hurt. Society also looked much differently upon DUIs 20 years ago.
Today, I'm now 45 years old. I haven't had a DUI in over 20 years. But I still do stupid things.
I'll likely go up to the store today to buy a pack of cigarettes. Why? Because I'm still an absolute moron in that one aspect of my life. I'm smart enough to know that nothing good can come of smoking. But I'll buy a pack. And I know the consequences.
100% self-control is difficult for a large amount of people. Whether it's drinking, drugs, smoking or eating too much--it's a struggle for many.
I believe it's extra challenging when mixed with youth, fame and millions of dollars.
