Perhaps, I simply never wanted to see the negative. Surely, I was quite naive. But, I think it was more due to a force within me that wants to help people become the best that they can be. Yet, at the time I didn't realize that such a motivation had to mostly come from within.
In reality, one's true potential can only be realized by the self. This became painfully clear to me after years of trying to help some very poor cases. There are those that because of painful circumstances in their home lives, they never had a good chance to truly realize actual love and affection. I felt by offering these things that I would offer them a true chance to develop into the best possible people that they could have become. To the best of my knowledge, many of them went on to lead fairly mediocre lives to varying degrees. Some turned out better than others, but most I never heard from again.
When I'm writing my stories, I always try having this sort of naive, good-natured character with only the best of intentions. I've even had a main character in a story that wants to only see the good in a man who truly acts too good to be true. That man, in fact, does turn out to be quite evil. The strange part of it is that because of her blind faith in him, he actually does fall truly in love with her.
This love that she feels for him causes a similar reaction in a once cold and dead heart almost leads to her ruin. Her love for him and his love for her, however, sadly is not enough to overcome the darkness that controls his destiny. If not for her friends, our main character would have been destroyed.
This is why it is good to have friends looking out for you! Those that know you well will hopefully cover for your weaknesses in times of peril!
Each of us constantly has to keep a balance between the good and evil within ourselves. Walking that fine line between those two is very difficult. Every day we must decide between those choices that will help and those that will hurt ourselves and others which constantly present themselves.
Yes, seeing the good in others is something we can use in order to provide a support mechanism for those that need a good friend in times of need. But, it can never be allowed to blind you. Only pain can come from the failure of seeing someone you thought was good turn against you. Perhaps, it may even destroy any chance of that good potential ever being realized.
As the French say, C'est la vie!
