If an ordinary cultivator got their hands on the flag, they would definitely kill people for power. If they killed too many people, they would indulge in the pleasure of killing. The flag had another ability, which was to absorb the power of other souls and blood and flesh, and then transform them into Dharma power and blood Qi to supplement the person holding the flag. If the cultivator's will was not strong enough, he would indulge in the pleasure of killing people. If they continued to gain power from the sinister Wind Ghost flag, they would eventually become murderous maniacs.
