Great, we agree you believe you should follow an unethical law.
> All of them. I still expect foreign ones to follow our laws, and us theirs, because to not do so is also unethical.
Great, we agree that you justify it as not unethical because its the law / practical / what others do.
You are justifying actions as something you think should be done, and reasoning that because you want it to be done, that it must not be unethical.
Justifying evil because you think it is worth it is one thing. Concluding that evil is not evil because you think it is worth it is the scum of society.
