Medea and Revenge

I don't think that revenge can ever really be justified. However, I think that forgiveness, in the sense of waiting to forgive or maybe not being able to fully forgive someone, can be justified. I have found this to be true from my own life experiences. I have even found myself trying to get revenge on my own family members, by not acknowledging them and ignoring them to make them feel bad to get back at them for whatever they have done to me. This is when I found revenge is never the answer, because it did not make me feel better in the long run. 

I think that Medea is in the right to be completely upset at Jason, and to not forgive him, but I do not personally think anything is worth a human life/lives. The controversial part is that she has no choice with her love for Jason. That is where I think the situation can be justified, because she is technically mentally unstable.
