I equate Hitler and Lincoln in a biblical reference as both children of God.
Please establish that either was a "child of God" in the "biblical sense". In John 8, Jesus called men who were in the moral sense greatly superior to either of those men... children of Satan.
As a fallible person myself it's not on me to judge others.
Where did you get that idea? It is not in our power to condemn people. But there are numerous commands in the NT and examples both from Christ and the Apostles showing that we are to take stands against evil behavior. Do you recall the story of John the Baptist? Jesus called him the greatest of all prophets. He was beheaded for "judging" Herod's adultery.
Even in rescuing the woman caught in adultery, Jesus commanded her to "go your way and sin no more". 1 John is one of the "love" epistles and is full of "judgment". Matthew 18 establishes that if someone is known to be in habitual sin that a person has a responsibility to confront them. If they do not respond, two are to go. Eventually the church is to remove that person from the congregation until they repent.
Practically the whole book of 1 Corinthians was a rebuke of behavior within that congregation... which included acts considered incest. There is at least an allusion to some returning to homosexuality.
The abuse of the "judge not" passages is not "Christian" in nature. It is worldly. It is a carnal attempt to "make peace" with sin.
For historical reference, I would ask the native Americans what they think of Lincoln, and then what they think of Hitler. Most who know their history would place those two a lot closer to each other than some falsely assigned heaven/hell dichtomy you think it is.
I didn't assign such a dichotomy. Christians have tried to lay claim to Lincoln and I have no means to know his heart. He made Christian affirming statements but politically he needed the zeal of Christians who were the driving force behind ending slavery.
If you do not think Lincoln was better in the temporal, human sense... in the sense of general character and intentions... than Hitler. You truly need some help.
We can have a discussion on American Indians if you like. There were some grotesque abuses of them at various times. But the idea that Europeans came in and attacked them and "stole their land" is WAY off. The best estimates for Indian population in ALL of North America when Columbus arrived... is about 40 million. That's Panama to the Arctic. For reference, grab a world map and look at California. The entire population in NA in 1492 was about the same as CA now. IOW's, there were wide expanses of unused and undeveloped land. Far from being a "change"... Europeans were just a new, more technologically advanced enemy. The tribes didn't live in some sort of peaceful, unspoiled Eden. They attacked each other over land claims. They raided and killed each other for food and supplies. They stole women and children. They enslaved one another. You like many today see them as a single group. They NEVER saw themselves that way.
Even in all of that... the greatest harm done to native tribes was NOT bullets or intentional. Europeans brought diseases that previous plagues had left them greatly immune to. Disease was the cause of death for most natives who died... not exposure or sabers.
There is no comparison between the actual intentional abuses of the native Tribes... as bad as they were... and Hitler's very intentional slaughter of people he considered inferior and obstacles to his master race. Lincoln's part in that... wouldn't even come close.
