People who destroy other people in the name of religion, if they don't have God's direct command to do so (which they don't in this modern day and age), they are doing wrong.

At times Islam uses the threat of death to force someone into their religion. This is absolutely the wrong way to do things. An infinitely better way is to invite, showing the advantages of joining, and the disadvantages for not joining, and then letting the person make up his own mind.
