Even Ramayan Teaches Dont follow religion Never trust Sadhu or Pandit

In Ramayan ,
                      If Sita wouldnt have trusted Sadhu ( disguised Ravan) and not corssed Lakshman Rekha. A whole war could have been avoided.
Killing of Kumbhkaran (an obedient brother) could have been avoided.
Learning : Never trust Sadhu/Pandit. Dont be blind in Religion.As hindu religion says sadhu should not be returned from door step without bhiksha. But when Sita followed it Janta of srilanka and Vanar sena paid an hefty price.
