In attempting to help those with whome one has no true raport, naturally there is suspicion.
"Does this person have ulterior motive, or do they truly mean to help?" or conversely; "Do I only do this for the benefit of my own Karma?"
Outside of possible cases where additional assurance from the reinforcing party can somehow be considered as material evidence, wouldn't such reassurances only arouse more feelings of suspicion?
When a truly kind deed is done, those reinforced may be moved to say "there are no words". The Tao te Ching says; "The way that can be named, is not the eternal way".
