The 4 Main Yoga Paths/Margas

Towards the end of last class we discussed the four main Yoga Paths or Margas that a person could take to achieve the goal of being free from the material world and living life truly free(Moksha). Anways, I was kind of thinking to myself a little later about this concept. A person could take any of these paths and get to the same goal, but the thing is that the Jnana Yoga, Raja Yoga, and Karma Yoga are all harder than going by the Bhakti Yoga path to attain Moksha. So therefore, is it more fulfilling to take the harder Yogas? If a person was to go through the easier Bhakti Yoga, would their goal to Moksha feel less rewarding or deserved? I wonder if anyone would point fingers to someone who just went the Bhakti Yoga path and blamed them for attaining true liberation by cheating their way to it. Since the other Yogas require serious and focused mental, physical and spiritual discipline, I would have to think that a person on these paths would feel kind of angry at someone who took teh Bhakti Path. But on the other hand, attaining true liberation/spiritualism would require someone to release their anger/jealousy and realize that everyone has the natural right to choose whatever path they want. I mean, The Bhagavad Gita laid out these paths for everyone to choose, not force to use a certain path for a certain person.
