 But it seems possible that individuals might engage in shared activity (and have the corresponding intention) even when they have different and incompatible reasons for doing so. For example, representatives from rival parties might engage in the legislative process that leads to the passage of laws, even when each is motivated by considerations that the other finds  unacceptable.[19]  Still, it is plausible to think that there must be some constraints on the sort of individual motive or reason a participant has to engage in shared activity. If my motive for engaging in shared activity is overly manipulative or undermining of fellow participants (e.g. doing something with A in order better to control him/her), the status of the activity or intention as shared might be  compromised.[20]
