I am wondering what evil is. It is a very difficult question to answer and the answer is very ambiguous.
First of all, evil is everywhere, where people doing something wrong. For many people something can be wrong, whereas the others think that it isn't so bed. Evil wouldn't exist without people. For most of us the word "evil" is associated with murders and thefts or even with our small lies, drinking alcohol, smoking cigarettes and using vulgar words. None of us is criminal, but all of us have something on our conscience.
However everyone has his own conscience, he considers different things as evil. For many of us creating the line between what is right and what is wrong would be extremely difficult. What is more, many times the line between these two things is very easy to cross.
Our world is full of violence. Nowadays, small children watch cartoons full of brutal scenes and blood. When they grow up they probably have some problems to recognize what they do wrong and right. Parents should take care of what their children watch on TV. That would be necessary to bringing up their children properly. Parents should be for their children an example of good behaviour. All external factors such as school or friends have an extremely big influence on young people. Unfortunately, some of them chose criminal way in spite of the fact that they try to do everything good. The environment we stay in influences on us. The effect of environment can be better or worse.
We should try to be good people. We should destroy the evil, which might be inside us. Every one of us can estimate what is wrong and what is good.
