Sure you can. I think it's wrong to murder people for no reason. I say something like "government should avoid baseless murder." Maybe I'm offending people who have deeply held pro murder beliefs, but I'm right and they're wrong.
I'm making a joke here, but to illustrate the principle that just because a country has some tradition or practice doesn't mean it can't be criticized. There is such a thing as objective reality.
And of course we have to recognize that we ourselves can be mistaken about the truth so it's smart to practice a degree of humility and introspection when it comes to people we disagree with. Even so, I'm pretty comfortable saying that laws which imprison people for criticizing a king are counterproductive and harmful to a society.
