A challenge about women and marriage in Islam

[SiRade]

Assuming that Islam is the correct religion
By killing apostates you reduce the number of other people who can follow (and go to Hell)
Which is good (giving that Islam is correct)

Now can you show/prove that it can be something bad?

And without assuming anything? All it does is removes opposite idead, how is this good in any way? And why when Danish cartoonist draws 12 muhammad cartoons whole islamic world goes nuts and when normal people draw 12 000 muhammad cartoons, all muslim countires do is block internet (or some webpages)? And how is this system your talking about better than any existing systems? Please, shun some light into my infidel eyes.
Oh, and could you provide your "scientific" sources again, but this time please specify authors, year published and journal.
