Doubt and contradiction in buddhas teaching I have few doubts in buddha teaching. Just wondering my mind since i start reading the various teachings.


Lets assume we all achieve the enlightenment then what will happen to world? No one will exist .. no life will exist... that will be the end of this universe.
If we really know the path then why even one percent leaves behind and could not achieve nirvana.
Buddha says we lose what we cling to. But he talks about love too.
Loving your son or wife will bring attachment for sure. 
What one should do when a person rapes/molest your close one in front of you? Anger and emotions will take over.
No need to worry about this scenario. Even during the Buddha's time, at the peak of the Dhamma, how many people attained enlightenment and how many did not? By the way, with or without enlightenment, the universe will go thru periods of birth, decay, and destruction. It's inevitable that one day life as we know it will cease to exist. And one day, life will spring up again. Hence the endless cycle of Samsara.
Well, as the saying goes, there's a big difference between knowing the path and walking the path.
One can equanimously execute countermeasures to incapacitate a rapist or molester without letting anger arises. Matter of fact, martial arts practitioners are trained to keep a cool head. Anger, rage, fear, etc. only cloud one's mind and make it much harder to handle rough situations.
