It can if taken out of the proper context in which it was taught in the suttas. The Buddha taught that mindfulness is to be practiced with patience, harmlessness, loving kindness and sympathy:
SN 47.19. Sedaka
On one occasion the Blessed One was dwelling among the Sumbhas, where there was a town of the Sumbhas named Sedaka. There the Blessed One addressed the bhikkhus thus:
“Bhikkhus, once in the past an acrobat set up his bamboo pole and addressed his apprentice Medakathalika thus: ‘Come, dear Medakathalika, climb the bamboo pole and stand on my shoulders.’ Having replied, ‘Yes, teacher,’ the apprentice Medakathalika climbed up the bamboo pole and stood on the teacher’s shoulders. The acrobat then said to the apprentice Medakathalika: ‘You protect me, dear Medakathalika, and I’ll protect you. Thus guarded by one another, protected by one another, we’ll display our skills, collect our fee, and get down safely from the bamboo pole.’ When this was said, the apprentice Medakathalika replied: ‘That’s not the way to do it, teacher. You protect yourself, teacher, and I’ll protect myself. Thus, each self-guarded and self-protected, we’ll display our skills, collect our fee, and get down safely from the bamboo pole.’
“That’s the method there,” the Blessed One said. “It’s just as the apprentice Medakathalika said to the teacher. ‘I will protect myself,’ bhikkhus: thus should the establishments of mindfulness be practised. ‘I will protect others,’ bhikkhus: thus should the establishments of mindfulness be practised. Protecting oneself, bhikkhus, one protects others; protecting others, one protects oneself.
“And how is it, bhikkhus, that by protecting oneself one protects others? By the pursuit, development, and cultivation of the four establishments of mindfulness. It is in such a way that by protecting oneself one protects others.
“And how is it, bhikkhus, that by protecting others one protects oneself? By patience, harmlessness, lovingkindness, and sympathy. It is in such a way that by protecting others one protects oneself.
“‘I will protect myself,’ bhikkhus: thus should the establishments of mindfulness be practised. ‘I will protect others,’ bhikkhus: thus should the establishments of mindfulness be practised. Protecting oneself, bhikkhus, one protects others; protecting others, one protects oneself.”

Liberation is the inevitable fruit of the path and is bound to blossom forth when there is steady and persistent practice. The only requirements for reaching the final goal are two: to start and to continue. If these requirements are met there is no doubt the goal will be attained. This is the Dhamma, the undeviating law.
