There is some truth to the old saying, "time heals all wounds." This has a lot to do with the way our biological memory works. Unless a specific event is replayed frequently in our minds, the details will fade. Even the act of replaying a memory can change it in small ways. The fallacy of human memory and it's unreliability is related to its maliability and it is partly this maliability that allows us to forgive and forget as harsh memories are softened with time.There is also the basic undeniable fact that Hatred is subtractive, while Love is additive. Practically speaking, this seldom means much for us mayfly mortals...but live long enough, and no matter how strong your hate, if it doesn't receive new fuel, it'll go out. Of course given how Echo got screwed, that may well take a few hundred thousand years. (Though I wonder if the speed at which A.Is think/feel would cut that down in "real-time"?)
In the case of a digital being, with perfect memory, perfect recall and all the complex emotions of that moment available to relive at any time, can we really assume that time alone will heal Red's wounds? Or Echo's? Is it more realistic to think that their hatred may only grow unless it is actively curbed by new input, new memories?
I don't know, but I hesitate to translate such aspects of the human mind to our digital protagonist.
