What Is Evil?

In my hometown, Oakland, CA a few weeks ago, Jin Cheng Yu, 27, and his 59-year old father were walking down a street.

For no reason, two men approached Jin and started punching him. When his father interceded on his behalf the two men beat him to death.

A few days later, the lawyer for one of the accused stated, "this is not a murder case...(my client) is not an evil person."

Really?

I wonder
