Start from the assumption that people are well meaning and intentioned, do not jump to conclusions without first asking or discovering what the intended conclusions were/are. If it is discovered that their intentions are just, and are informed that their means will not achieve just ends, they may be open to amend their means so as to achieve a more just outcome. If their intentions are not just and the outcome is not just then the person or group can and ought to be held responsible for their actions, punished if necessary, but excluded from full participation in the community with all the relevant privileges until such time that the harms is rectified and the relationships have been brought to reconciliation. Either way, by assuming honorable and just intentions we do not unfairly attribute blame and harm upon those who mean well while contending in an uncertain world; that would prove to cause more harm to the community than good.
p.s.
Those who will openly conceal their true intentions will not only be more trustworthy, but will reveal themselves to the desirable community members. However, those who seek to conceal their true intentions will tend to have motivations in opposition to the health and sustainability of the community. Knowing their intentions would reveal that they do not belong in the community and are thus hoping to free-ride on the agreement and compliance of others at the cost and the risk of the community.
