also by killing his own sons and serving them as food he was considered to actually of broken laws so dire even the Olympians could not tolerate it (as in any of them) - the mythology gods were quite fickle creatures and while they enforced laws it was often random laws they made up for themselves.. Tantalus broke a law that was beyond the pettiness of the gods and basically would be considered the same as unforgivable sin in other works.. plus I don't think he ever actually felt remorse over doing so.
