Are humans dangerous and should they be controlled ?

Humans are dangerous since the beginning of creation , the famous story about Cain killed his brother  Abel , Adam's and Eve's sons. The story gives us an example about how humans' anger led them to do dangerous actions if they don't get what they want.Again, Humans are the most dangerous animal on earth. We have killed more of our own kind than any other animal on earth. We have destroyed more ecosystems than any other animal. We have made species extinct more than any other animal. Unlike any animal on earth man has created things never found in nature that kills. No animal on earth other than man has created bombs, poisonous chemicals, bio-toxins, cars, planes, heavy machinery and all the other billions of things that kill directly or indirectly. The development of the  individuals and the countries make humans greedy and they can take dangerous discussions to get what they want and this is really sad.

But at the same time we can't be controlled because we are actually controlled by our needs and things we love. The development we are seeing these days may let the humans to change their way of getting their needs. Humans start to wake up and think somehow about what they are doing. They can be better than they are now  but we need the chance to look about what we are doing so we can change to be better, and we are starting to do so, it is about the word POWER and if it does not exist everything will be okay because , what we are seeing these days that people are becoming dangerous just to get to power, UNFORTUNATELY ! it is about hope and hard work to change our way of thinking to get our things , violence and dangerous dissensions are not always the way to get what we want.
