Yes government can kill bitcoin in the way how they want to do it for example if there no more people who are appreciating bitcoin they can kill it easily
How can they kill Bitcoin "easily", why haven't they done it already if this was indeed the case? Bitcoin is decentralized and has a format to prevent any manipulation from a central figure. Only certain aspects of mining is somewhat centralized. Trust me if it was so easy to 'kill' Bitcoin then it would of likely been done already. I mean it's had several attempts on it, but as of today all have failed.
Yes its true, if the Government can easily kill bitcoin i think they kill it before the bitcoin is not popular. Bitcoin cant easily kill because if its easy then it already replace by another crypto currencies, because there are lot of people wants to copy the format of bitcoin but they cant do it.
