Was Socrates crazy for trying to wake up the people of Athens?

One could argue that since Socrates was eventually sentenced to death for heresy, he was at least imprudent, in his philosophical teaching. But on the other hand, had he lived a cautious and prudent life, keeping his ideas to himself to avoid causing controversy, no one today would remember who he was. It may be that his accomplishments, as one of history's most influential philosophers, outweigh his shortened lifespan. In any event, I would not call Socrates crazy.
