No No and No (Score 1)

1-you don't need to take a virus to see a nice piece of code. I'm sure some things like demos are also REALLY nice pieces of code 2-when you write a program, you offer somebody the possibility to do something. for a 'normal' program, you give the user the possibility to achieve a certain kind of work. when you write a virus, you give him the opportunity to do nasty things he could not have done without you (well, without you and the others virus authors. but let's forget the "i'm no the only one!" excuse). So YOU are responsible.
