Can ordinary people do evil? Why are humans so comfortable hurting each other? Is there a line where human compassion finally kicks in?

Yes, ordinary people can do evil. Anyone can perform evil acts or act evil. We are animals that have formed a society based around love, but love and hatred come from the same place. Love and hatred (which cause us to do such evil things,) are extremely strong emotions. When we are too overwhelmed by such hatred, we forget our compassion and let rage take over to perform evil acts. When the hatred calms, we see what our emotions have led to, leading to feel compassion for those we hurt. It is also in our natural instincts that we compete with eachother, much like other animals. This is why we are so comfortable hurting eachother.

Hope this helps, sorry if it is too long! :)

a biography is a genre that mainly accounts somebody's life and that is written by somebody else. this genre supports sonia nazario's desire to share enrique's life because she can fully inform readers of his entire emotional journey.

in a biography, an author can share the readers almost everything about a person's life, or just one key event or personal aspect the author is interested in telling, like in this specific case in which sonia nazario is centered in enrique's emotional journey.

the answer is c because info security should not use them for code
