Suttee is still reported, but very rarely, usually in remote rural districts. I can't see how anyone could deny that men's burden in war is by far the worst. In some wars civilian losses can be relatively large compared with combatants. Even then, about half the civilians are men. Invaders often kill civilian men and even boys outright.
Women are less likely to be killed.
For the United States the ratio was fifty to one. The USSR alone is reckoned to have lost eleven million soldiers, compared with the six million European Jews of both sexes murdered by the Nazis. Soldiers of course undergo hardship and deprivation, and for every death several men were wounded or crippled. On top of that, many of these men were captured and imprisoned, or tortured and brutalized in any number of ways. It's simply no contest.
