Darryl Strawberry does not need our sympathy. He has been given chance after chance to help himself. His time now should be spent in jail, where outside influences can have little effect on him. Being removed from society may be the only way to help him. He obviously has a problem, but has not yet found the solution.
Substance abuse is a complex problem.
It is said that it is a disease, and it is something that never goes away. So it seems the best way to allow Strawberry is to remove him from any influences where he can be tempted. And maintain the hope that upon his release, he will have the common sense to stay away from temptation as well. This time he is not playing a game, as he has spent so much of his life doing. This time he needs real help, from real people.
