How did the Council of Nicea in 325AD harm all Christians ever after their meeting?

Basically, what they did was to create Jesus as a Diety so no one every could be like him ever again, man or woman. By deifying Jesus they stole from all Christians the right to believe in Jesus the way that they wanted to and created soldiers killing anyone who believed something different than what the Council of Nicea set forth. So, millions of people were killed after this just for believing ANYTHING different than what the Council set forth throughout Europe and into the British Isles. This council basically honored the rights of Kings and Queens over the rights of all humanity on earth to believe whatever they wished and so over time millions were killed and tortured to honor the Kings and not the people of earth.

 Answer: The Council of Nicea took place in AD 325 by order of the Roman Emperor Caesar Flavius Constantine. Nicea was located in Asia Minor, east of Constantinople. At the Council of Nicea, Emperor Constantine presided over a group of church bishops and other leaders with the purpose of defining the nature of God for all of Christianity and eliminating confusion, controversy, and contention within the church. The Council of Nicea overwhelmingly affirmed the deity and eternality of Jesus Christ and defined the relationship between the Father and the Son as “of one substance.” It also affirmed the Trinity—the Father, Son, and Holy Spirit were listed as three co-equal and co-eternal Persons.

Constantine, who claimed conversion to Christianity, called for a meeting of bishops to be held in Nicea to resolve some escalating controversies among the church leadership. The issues being debated included the nature of Jesus Christ, the proper date to celebrate Easter, and other matters. The failing Roman Empire, now under Constantine’s rule, could not withstand the division caused by years of hard-fought, “out of hand” arguing over doctrinal differences. The emperor saw the quarrels within the church not only as a threat to Christianity but as a threat to society as well. Therefore, at the Council of Nicea, Constantine encouraged the church leaders to settle their internal disagreements and become Christlike agents who could bring new life to a troubled empire. Constantine felt “called” to use his authority to help bring about unity, peace, and love within the church.
