The intention of the IMF is not to help those it gives money to. The intention is basically to control them.
If you accept money from someone, don't be surprised if they try to put conditions on how you spend the money. When you're begging for money in the international market because no private investor will give you a loan due to your reckless spending behaviour, don't be surprised that donors ask for conditions on how that money is spent. If the Greeks didn't want conditions, they could always radically cut expenses to meet tax revenues and not be dependent on any handouts to make the budget balance.
