No valid religion is about suicide and/or killing other people's children.
An interesting point, though religion is generally pushed off in the realm of the subjective as are nearly every method of measuring a religion's validity.
More interestingly is your point about children. Taking the chance that someone will accuse me of being a fan, "Sting" wrote a song twenty years ago, at the hight of President Reagan's deployment of mid-range nuclear missles in Europe entitled "I Hope the Russians Love Their Children, Too."
One essential difference, very broadly speaking, between the clerics of "Radical Islam" and the same atheist priesthood running Soviet Russia is the former's unhesitating willingness to kill anyone and everyone.
Again, BROADLY SPEAKING, an examination of Islam and shows they really may not "love their children, too."
In a display of "Orwellian Logic" (one of many in the islamic "play book", the Koran condemns suicide but is interpreted to ignore this admonition when it is a "Martyr" involved in the act. In addition, their killing of children (whether their own or others) merely accelerates a "believer" into paradise or..., eliminates an "infidel" who is "an abomination in the eyes of Allah"!
At some point in time, the west will learn to deal with the islamic mindset in a manner which accomplishes both parties' interests...
Islamists seek death as a means of being "rewarded" in paradise so, their deaths (by the millions) will please them and..., eliminate their threat to western civilization!
One exception : Islam.
