According to you, who is more dangerous: good people or bad people?
Whatever you say, chance is that you are not perfectly right.
This is because of the fact that both are equally dangerous. Since, bad people are bad so they will harm you without any mercy. But, I feel that in today's scenario, even good people can be dangerous and sometimes more than the bad people.
Reason
Since bad people have never been good so they don't know the mental trauma which a good person has to undergo when they are tortured by bad people. But when good people turns bad then in such case they have complete idea of what it feels when you are tortured. So, they are crueler as they know the threshold of pains and sufferings. This cause them to cross the threshold limits more often.
Also, since they were forced to become bad due to world's harshness so they have lost all mercy whatever they had possessed and become mentally sick and only believe in taking revenge from world. In this process they loss interest in world and live solely to take revenge. This makes them fearless and was no more afraid of death.
Now, only way to prevent such problems is to protect good people rather then corrupting them. So, now I thin that you have got the sufficient idea about this topic.
