In this context, ‘madness’ implies someone who might be perceived as unconventional or eccentric. It suggests that the more 'crazy' women can be in terms of outward behavior, the more kind-hearted they really are. It’s often used to convey that unconventional women often tend to be misunderstood but have big hearts.
