I never believed that someone could be truly cold-hearted. I thought that even the worst people must have had some amount of good in them. Once I first heard about (random name), though, my thoughts started to change. Hearing about the savagery of their actions was the start. Then I saw (random name) for the first time. They were swaggering down the path in an uncaring but confident manner, as though they had done no wrong. I stood tongue-tied, watching them get closer and closer, then I realized (random name) was walking towards me!
