There's nothing wrong with using steroids or other performance enhancing drugs. What's wrong is agreeing to abide by a set of rules and then breaking that promise.
That said, the ethical situation gets trickier when rules are not enforced, not enforced equally or if most or all participants are violating them and getting away with it.

Heretic!
