1) in the USA slavery would have eventually ended due to the economics. Steam engines are cheap compared to human manual labor.
2) Migrant labor is the replacement for slave labor in the USA. These are workers who do not legally exist and thus are subject to the worst of exploitations by employers and criminal concerns.
3) Human beings of all races have a pretty bad record of how they may treat other races/tribes/outgroups. Genghis Kahn killed and raped so many people that he altered the genetic profile of humans. African tribes routinely enslaved each other. Arabs took white slaves. People can be dicks. The list goes on and on: cruelty is a part of the universal human condition.
As bad as the USA, it's the only country to go to civil war to free slaves of another race, even if that wasn't the complete reason for the Civil war.

"free slaves of another race"? Some of those going to war were people of that race. On both sides.
This is also a bit ahistorical as Lincoln was willing to allow slavery in order to keep the union. It was really the south who chose to go to war in order to guarantee slavery would stay; the north chose to go to war in order to keep the union. The slavery issue was used by the north, initially, to keep the anti-slavery UK from siding with the south.
Eh, the US went to a civil war because half of the country (the south) started attacking national (i.e. union) armories/forts.
Of course there was some lead up to that but the actual flashpoint is that the south started it and they didn't do so to free northern slaves. Northern congressmen were not pushing for any bills that removed slavery from the south and etc; there wasn't an imminent (i.e. during Lincoln's presidency) existential threat that the North would end slavery in the South except the one the South manufactured.
Not in a form that could replace slaves. The first traction engines were not until around the civil war time, and those were not practical for many tasks that slaves did. Steam trains did exist, but the idea of running a train engine off of tracks didn't really come around until the 1850s - just before the war - and those were very limited machines that couldn't work most soils.
Even at that, the steam engine was in the process of replacing slaves for many tasks. There were just a lot of tasks left that the steam engine wasn't yet practical to replace slaves - but that would have happened anyway.
