What were Columbus' intentions? What were the results of the implantation of his intention?

Christopher Columbus wanted to find a new, and quicker route to the Indies, which were a viable source of income. He believed that going across the Atlantic ocean, he would get there much faster. As it was, it took months to get to the Indies, around Africa and through the Indian Ocean.

He didn't succeed, but discovered uncharted lands in the process. He believed he was in India, thus he called the Native Americans "Indians". His success, however, wasn't good for the Natives. Diseased pillaged large groups of people, and the subsequent conquests by European 'adventurers' wiped out much of the Native American population, and created disastrous cultural effects that would last for many generations.
