If by 'similar' you mean both believe that non-adherents go to hell, yes.
But the difference is, the Christians are taught by scripture that, if someone chooses not to convert, they are to leave that person's future to God. In Islam, if someone resists, the Quran teaches them to kill the infidel.
By the way I dont buy the argument that Islam teaches people to kill and Christianity does not. It all depends on how you interpret it. Christians who carried out Inquisition, Crusades and killing of Jews and Pagans did so with a firm belief thats its their religious duty. Of course such practices are condemned now.
As long as you have a religion that sees humanity not in terms of general good and evil but in terms of believers and non-believers, there will always be those who will associate non-believers as evil and will take it upon themselves to rid the world of “evil” (non-believers).
IMO anyone who believes that not following a particular God will earn him/her hell, is only labouring under false indoctrination with no real understanding of God and has submitted himself/herself to be used as a tool in the hands of a quasi religio-political authority. Its no longer a religion but a mental disease or a virus that makes the host desperate to infect others with, through feigned compassion, guile or outright force.
