There is no potential for harm that exists because of GMOs that did not already exist prior to GMOs. Indeed, because genetic modification is targeted, the potential for unintended consequences is far lower than with any other husbandry technique ever used. Your objection is analogous to objecting to snipers being used on the Western Front in WWI on the grounds that snipers might miss their intended target and kill a civillian; so we should ban snipers, and stick with the tried and tested 'machine gun' and 'massive artillery bombardment' techniques for killing enemy officers.
Please let us not be confused about Monsantos motives, which are corporate profit.
No matter how nefarious, nor how benevolent, their motives, the science remains unchanged. If what they are doing is risky, it is risky regardless of benevolent intent; and as what they are doing is not risky, it is harmless regardless of nefarious intent.
Please let us not forget that big business has a long history of promoting the beneficial and sometimes 'beneficial' aspects of their products while sweeping valid concerns under the rug.
Big business also has a long history of promoting the beneficial and sometimes 'beneficial' aspects of their products while defending themselves from spurious claims of harm. Which they are doing in any given case can be decided by science, but cannot be determined from history.
Look at Nestlé's promotion of formula for babies, first in the 'modern' west and then in developing nations.
OK, I am looking at it. It appears not to have involved genetic modification, so it really is not at all relevant to the question of GMO safety.
If we are truly concerned about saving lives and promoting better health in developing countries, we would be working a lot harder at promoting access to reliable sources of clean water. We certainly would be doing more to prevent armed conflicts and political instability. I suspect Monsanto hasn't found a way to make a profit on those initiatives.
Well, if you were truly concerned about saving lives and promoting better health, you would have become a doctor. I suspect that you haven't found a way to make a living as a doctor.
Of course, that is a ridiculous argument; You have chosen a career path for any number of reasons, and you don't treat sick patients, not because you don't care about them, but because it isn't your job - you are not qualified to do it, and you can do more for society, and for yourself, by doing your own job as well as you can.
It isn't Monsanto's job to dig wells for African villages, or to solve world conflict, any more than it is your job. Monsanto sells seed to farmers. They try to sell the best seed they can produce, at a competitive price. That's what they do. Whether or not any of their products are harmful is a matter for science to determine. It cannot be determined by looking at their failure to dig wells for poor villages in the Sudan.
