I was surfing the web looking for a gun to buy illegally
Why buy a gun illegally?
Because I can. It's a nice day for it.
Just because you can is not a sufficient to justify an action. If you must purchase a gun, why not go through legal channels?
Because I want to be an outlaw.
Buying a gun illegally will certainly make you a criminal, but this isn't something that you should aspire to. Whatever satisfaction you will get from living outside the law will be insignificant compared the consequences you will face when you are inevitably caught.
