it’s our experiences in life. We process things the same way everyone else does, which is the reason psychologists can help people. It’s because they have gone deep into the mind of one person and it could apply to everyone.
With that in mind, does it make our society the reason we fall under the power of the weapon? Of course not. The society revolves around the people and the wealth or items. So both impact how we think, but which gives more? The question keeps coming up of which provides more influence. For the true answer, we have to dive into history. We have to think about the one who first killed. Of course there is no real evidence, but a look into psychology will reveal a deep want of being like that person. So, when the first kill occurred, another was persuaded to react the same way.
But did the first person to kill actually kill? Most likely, he/she was overwhelmed by the power of the weapon. So truly, anything with a good purpose will eventually become evil due to its overwhelming strength (even a rock).
