US foreign policy under Teddy Roosevelt was rather heavy handed by modern standards, but remember, this was long before the United Nations existed. Today the US would do things differently, but the way in which the Panama Canal was built was acceptable at that time in history.
The United States assisted in a Panamanian revolt against Colombia, and Panama became an independent country.
The United States encouraged Panama to gain independence in order to construct the Panama Canal.
The U.S. encouraged Panama to revolt from Colombia and quickly recognized the new government when they did. They also paid Colombia a large sum of money as compensation.
It is not true that Colombia granted freedom to Panama in return for income from the canal. The United States paid Panama to lease the property and build the canal.
The United States formally recognized Panama as a nation on November 18, 1903. Panama has declared its independence from Colombia not long before that.
The United States never acquired Panama. The United States leased the Canal Zone, a strip of land across the nation of Panama. The nation of Panama won its independence from the South American nation of Colombia, as did Venezuela and Ecuador.

The United States, under Theodore Roosevelt, bought out the French equipment and excavations, and began work on May 4, 1904, after helping Panama achieve independence from Colombia.

In 1903 Panama had a Revolution and threw out its Colombian rulers. No roads existed so that Colombia could send an army to Panama and put down the revolution. When Colombia tried to send in an army by boat, a fleet from the United States blocked the way. The United States Navy had more boats and bigger boats than the Colombian Navy. Other nations recognized Panama and that made Panama a free independent country.
The Colombian government had been blocking U.S. plans to build a canal in Panama.
Simón Bolívar freed the area of northern South America and Panama on September 7, 1821 and this was called Gran Colombia. Venezuela and Ecuador split in 1830 and Panama was with what is now Colombia in a country called New Granada. Then it was briefly Granadine Confederation. The country's government reorganized under the name The United States of Colombia in 1863. The country changed again in 1886 to Republic of Colombia. In 1903, Panama broke free.
