Ramification - the impact of what has been said or done; the true result of an action or the true meaning of a statement; often these are deeper and more complex than first thought. There is no positive or negative tone inherent in the word ramification. Repercussion - when contrasted to ramification, this means the negative consequences resulting from an action or statement. The person that is hearing the statement or receiving the action does not agree with or like it and as a result "pushes back", meaning they take some opposing action. So, ramifications can be positive or negative. Usually if they are negative, they will cause repercussions since someone who is negatively impacted will try to do something to change the action.
