present tense
when we are describing events that happen in works of literature we should describe it in the present tense because literature is all about presents works although there a little of old works. literature is all about life characterization of humans because it deals with our emotions, feelings. it deals with prose, drama, and poetry.
Actions speak louder than words means talking about something isn't going to make it better, you should take action so it helps solve the problem. I wouldn't say it talks about proving anything wrong based on the definition.
