Is it suicide if you have the power to resist someone trying to kill you and don't protect yourself?

Like Socrates? He was ordered to drink poison, for corrupting youth, and he drank it. Is that suicide?

Or Buddha? He didn’t want to offend a poor man who offered him a meal that was bad. The Buddha died from eating spoiled food.

Or Jesus? He could have called upon God’s wrath?
Instead he allowed himself to be crucified.
