This is just GREAT, I really love it!! It's really satisfying to see the time passing and how well developed is the psychological problems and traumas that all the carachters have. Especially kenshin, who regret all the mistakes he had made, and the lives he took, and don't know how to pay for it.
Also it shows how we do have to surpasse our own traumas and continue to live on while getting mentally stronger.
We all do mistakes in life and repent about it, even so we should never let go of our lifes, but should always try to be a better person.
