What are they trying to accomplish? Depends on who you ask. Monsanto says: Feed the world, help the poor farmers, etc.
IMHO: Their practices suggest they are trying to monopolize the genome of individual plants so that only their specifically engineered "product" can be used.
Have you ever heard a dealer suggest the first taste is free? Yeah, well, so does Monsanto.
What is SUPPOSED to be good? They have the (as yet unmet) potential to develop strains that would indeed be less dependent on desalinated water, fertilizers, herbicides.
IMHO: The "successful" ones, like any natural organism have the other parts of the natural system adapt to their artificial adaptation. So now we have "Super Weeds" -bigger, stronger, less susceptible to mild herbicides. Now they require a toxic stew to kill these new stronger weeds. Not good for the environment. And again, once they sell you seed, you can't resell it or use your own seed gathered from your own crops, because Monsanto owns the genome and you can't use it without purchasing the license. Watch the documentary "Food Inc." A couple of good scenes with Monsanto goons in it.
I'd say suing farmers out of business and literally wrecking their farmland to keep them from engaging in a practice as old as agriculture (seed saving) might suggest they are less than stellar citizens of the planet. Selling seed that can only work with a specific herbicide- which by the way Monsanto will sell them for a price-; effectively blackmailing poor farmers to either use their product or suffer Monsanto's wrath.

Some struggles facing Indian farmers are detailed in the article "Seeds of Suicide: India's Desperate Farmers" on Frontline.<99> The transition to using the latest pest-resistant seeds and the necessary herbicides has been difficult. Farmers have used genetically modified seeds promoted by Cargill and Monsanto hoping for greater yields. Resulting debts from such gambles with genetically modified seeds have led some farmers into the equivalent of indentured servitude. More than 4,500 farmers have committed suicide, which some claim is mostly due to mounting debt caused by the poor yields, increased need for pesticides, and the higher cost of the Bt cotton seed sold by Monsanto.
And while they tout their best selling and most popular product: Round up as "safe"; they only mean safe for the things they want you to know about.
It's decimating the frog/amphibian populations:
