Either it be Rape, Murder, or War - All have one thing in common and it is "Man". So, it sounds like, If men are less masculine and weak - the crimer percentage of "**rape**, **murder** and **war** will go drastically low.
What do you think?
LOL - This is extremely funny provlem. See, I don't want to offend, but Asking "Should men be more masculine or less masculine" is exactly like saying - "**Should women be more beautiful or more ugly or less beautiful**?"
Rape, Murder or War all has not men in common but - "ego", "greed" & "jealousy" and may be other sin too.
I would recommend to chill and be more positive towards life.
