My general description of such a person is someone, anyone who encourages and inspires others to appreciate the positive qualities of life, such as, good hygiene, health, gentleness, contentment, and safety. These qualities may seem dull or cliche to many people, but anyone who practices these qualities and appreciates these qualities does find life much more rewarding as opposed to so many people who destroy their life with addictions, negative attitudes, slovenliness, criminal activity, despair etc.
Remove pathos as it is an emotional appeal.This seems to be ethos or theme.
