Question on Evil

As i walk today, i encounter several people that i know had done something that i know not nice to other. They seems to be okay and all things are fine. all of this experience making me wandering, questioning and think what should i do against evil?
my personality has been those kind that easy to give judgement to other, it seems God has "cursed" me with this gift to being critical when evil prevail. i couldnt stand to see people that hurt other. Its always been within me to tell the truth and trough the extend that many people felt bad after encountering their fault being noticed and condemned.
but as time goes by and still the question rise, what should i do against evil? I realize this is what i can do.
I realize that i will never beat evil. often i think evil is an action. but now, i think evil is a matter of decision. people has to decide whehter to harm or to love someone. Therefore, i will never win against evil. Every people has their right to decide to do things according to their heart. some however, does have an bad intention toward other, while the rest just thinking about themselves.
then one thing that i realize i can do, that i will never stand down agaist evil. though it might consume me on the process, what God expect from us is to stand firm agaisnt it. Let Superman, Batman, Spiderman, and Hulk deal with overcoming evil but as an ordinary person our duty is to not stand down and to take decision to be evil too.
It is also our duty to save people from those who are suffer because of evil, it is our call to protect them from evil, to redeem them from the evil itself. there always be evil trough all generations and there will be people that will suffer because of their actions. Some people might has the gift to beat them, but i believe God give some other the power and compassion for saving those that fall into evil.
i will never able to make those who do evil to turn and be good, its God duty. Only God can overcome and beat evil. however, i believe that on the same time God call us to save those who are become the victim of evil, those who are suffer because of evil.
Jesus prayer now become clearer to me "but deliver us from the evil one" He never ask us to beat the evil, but to be delivered from it. For us that has decide to follow this man named Jesus, His prayers should be our prayer too, and to fulfil this prayer God need us to deliver those who has been struck by evil.
