No, I do not think that the World Trade Organization is beneficial and lacks any type of leadership and intervention in economic affairs. I think that it is seen more as a figure head, and the WTO has never helped a country's economy grow or stepped into bad trades between countries.
If there were free trade for all then limits on resources would need to be considered more otherwise for example forests would be devastated which would have an effect on biodiversity and indigenous communities. Also it appears that it is selective in decision making and there is more of a western influence than power in developing countries hands. I would be interested to see what other people think however.
