If I steal an item I deprive a person of that item. But the manner in which it is stolen can also cause damage, e.g. breaking and entering. People in positions of trust are able to steal with minimal damage caused by the method of theft itself.

> a weakening of trust amongst everyone in society

That's a very vague accusation, and can apply to nearly anything immoral. MP should return any money due, have it's credit score damaged, and punished for wilful fraud - but I wouldn't compare it to violent theft, or B&E.
