P.S. As far as difficulty in recruiting suicide bombers, I'd think so. Still, the Centers for Disease Control says that in the United States in 2013 suicide was the 10th highest cause of death, over 41,000 cases, with a rate of 13 per 100,000 population.
If the will to live is a strong instinct, then this must either be lost or undermined.
In evangelical Christianity (or more broadly, Paulist versions of Christianity), the simple act of faith in Christ is (perhaps supplemented with baptism) enough to guarantee an afterlife in heaven rather than hell. By contrast, Islam is rather more uncertain about who gets to go to heaven. Islam conditions this much more on acts and on the inscrutable will of Allah, and some forms of fundamentalist Islam teach that martyrdom increases one's chance for a heavenly afterlife.
Now, if someone is raised in a hellfire and brimstone religious background, and there is some aspect of their life which is highly inconsistent with this (e.g., homosexuality), and if one combines these factors with failure in life and depression, then conceivably some combination of guilt, fear and the desire to atone and avoid punishment, and personal factors, might combine to predispose some act of "martyrdom" which simultaneously transforms a failed life into a triumph, wins the effusive admiration and respect of others, atones for sinfulness, practically guarantees entry into heaven, and ends ones temporal troubles in an "instant" death that (provided one is blown to smithereens) doesn't allow much scope for failure, incapacitation, or lingering death.
