Is it worth it?

In Philo. we talked about Socrates' decision to not escape from prison and to die. And how every action was either just or unjust and how they are defined. He said that he had to die because he had been sentenced to die, even though he was wrongly sentenced. His friend had everything arranged so he could escape and not die, but he felt that his honor and teachings were more important than his life. I am not sure what I think, I can understand that leaving undermines everything that he was talking about, but what good are you dead? Since we still learn about him today I'm going to say he made the right chioce.
