Renunciation and Negative Mysticism (Escaping from ones Dharma)

May All Beings be Truly Happy! Is it possible that one can see that everything they have tried has failed, in a worldly sense, and has brought about suffering for themselves and others: has been completely selfish in motivation, at most times; and the times when help was extended to others, had little effect on alleviation of any suffering. Much contemplation has been gone into very deeply on this subject. I have found that without Right Loving Understanding, one is lost and is subject to confusion and suffering. So my question is that it seems logical to stop and address ones own suffering, and become free from suffering, so that one can be a beacon of peace and sanity in an insane world: so I am drawn to the monastic life ... but, have been told that this is a path of negative mysticism: that one should be a part of the world, and find time for personal peace while maintaining a householder's responsibilities? I have failed time and again attempting to achieve this goal. It seems that society and the way in which it functions is deeply corrupted. How does one remain uncorrupted unless one is free from it? The most important goal at this point is to be free from suffering so one can be liberated and be of service to humanity. Can this be achieved in a corrupted world? In a future that had a respect for all living things and lived at a humane level of consciousness I could see this being possible.
