I have done things that normally go against my personal ethics or morals strictly on principle in response to something I felt was unethical or immoral.
No, and I wouldn't
No, but I would if the situation was right
Note that I mean things that *you* think are unethical or immoral-- For example, if you have no issue with pirating music, that doesn't count. If, however, you normally don't pirate music but were angered/bothered/troubled by a record company's actions in reference to a certain album so you went out of your way to pirate it, that would count.
In the comments, tell me what you did or didn't do! Or thought about doing! Or would do! Note that this is public so admitting to serious crimes may be unwise.
