Well—and keep in mind this is all my own opinion—this where the exhortation in many religions to think of others' good rather than what is merely good for oneself may come into play; when we pursue our own good at the expense of the good of others (which we wall inevitably do, to some degree), we increase the potential of suffering for some party (we inevitably will not get it right 100 percent of the time, of course). This then becomes part of the karmic cycle of blowback that we must endure along the path of return. Just my perspective.
