To describe a helpful person in sarcastic language, I can express it like this： "Oh, look, it's our 'Savior' who is here again, always ready to save the world with that infinite kindness. Whenever someone showed a trace of distress, he rushed over like a shark smelling blood, eager to show his 'greatness'. I bet he wears a superman cloak when he sleeps, always ready to dedicate himself to the small problems of others. This "saint" probably survives by drawing the gratitude of others, right? How should he spend the days when no one needs help? " However, I would like to add that it is usually inappropriate to ridicule people who are enthusiastic about helping others, because sincere helping behavior is an admirable quality. This kind of sarcasm is only used as a linguistic example, and does not represent a true evaluation of enthusiastic public welfare behavior.
