Sorry David, my question was very vague. Let me rephrase it more properly by giving an example.
A merchant commissioned a keris with the intention to enhance his status & prosperity. One day, a thief broke into his house, and the merchant had to defend his belongings by fighting off the intruder using his "prosperity keris". In the ensuing fight, the thief was stabbed & killed.
Now that the keris had tasted blood which is far from the intended purpose of prosperity talisman, would the keris still have that particular talismanic value?
I am asking you this because, a man in a village of my hometown, had to use his keris when a monitor lizzard intruded into his chicken coop & stealing / killing / eating his chickens. Out of anger, and without any other weapons at that time, he used his keris to stab dead the lizzard. Consequently, a week later he fell ill and became insane. As the modern medicine had no answer to his illness, the family members took him to see a bomoh / dukun / shaman. It was diagnosed by the traditional healer that the genie khadam within the keris had caused the illness, as the keris was meant to be used as personal protection against any unseen forces. So by stabbing the monitor lizzard, the man had somewhat insulted his own keris and of course the being inside
