There is no connection between citizenship and criminal offenses one may commit. Revoking citizenship is NOT a punishment/correction method according to the Criminal Code.
When you become a citizen, you assume certain responsibilities, and the country assumes a responsibility for you. If you are a bad guy, you steal, kill and cheat on your wife
you will be held responsible. There is a punishment for every crime. If the punishment for terrorism is hanging or chopping off your head, then so it is. But what does it have to do with citizenship???
