"Never Forget" To Heal, Not Hate

I'm weary of the "never forget" sentiment we so often express after a tragedy because I don't think it's usually meant as a door or a path to healing. It seems to me that it's meant as plea to remain wounded and to inflict harm on others as revenge. While I'm sure there are some people who claim to see the "never forget" declaration positively, I think it's never going to be pure for them; it will always be debased and corrupted by the negative side of the assertion. I don't know of an ideal solution, but whatever it may be it will need to contain the idea that the horrible acts of our past shouldn't rule our future.
