Yes it defiantly does forget and forgive,After all Sikhism is a branch of Hinduism. but if some one take advantage of poor public,like drugging then raping the woman of congregation I am sure even Hinduism will not forgive such person, these person needs to be brought to the public notice and punished for there mis deeds. As I said check it on you tube there are accounts from the television news from India about this saga just Google Dera Sacha Sauda you tube and see it yourself. Keep an eye open for the television news and newspapers. It is same situation as if a pundit in a mandir dress like Shri Ram or Shri Krishan ji maharaj then drugs the females coming to mandir and raping them,I bet no Hindu will tolerate that.
My respect to Shri Ramchander ji maharaj and Shri Krishan ji maharaj, the names have been mentioned just for example no offense to any one. Respected fully.
