No. Lord Krishna is very merciful and forgiving to those who want to stop sinning and change their lives for the better.
“Even if you are the greatest sinner, when you are on the boat of spiritual knowledge, you will be able to cross over the river of miseries, caused by reactions to sinful activities.”Lord Krishna, Bhagavad-Gita 4.36
This is yet another proof that Lord Krishna is God. He doesn’t send people to eternal hell or burn people in fires. He is so nice that even the sinners can be saved simply by stopping all sinful activities and surrendering unto Him. The main sinful activities are lying, animal killing (meat eating), intoxicating (drugs, alcohol, tobacco smoking/chewing), having relationships outside marriage, hatred, violence, anger, and greed. One should give up these sinful activities.
