Your problem is that, knowing so little about actual history, you feel perfectly free to invent "facts" to support your ideas.
In real history, as opposed to your fantasies, the "lust for power and money" began with Deep-South slave-holding secessionists, who first declared their disunion, then immediately started and finally formally declared war on the United States.
If you could simply remember that not a single Confederate soldier was killed in battle by any Union force, and no Confederate state was "invaded" by any Union army until two months after the Confederacy started war at Fort Sumter, and a full month after the Confederacy declared war on the United States.
By the way, that first Confederate soldier killed in battle -- on June 10, 1861 -- was Pvt Henry Wyatt, from Tarboro, about 100 miles east of Raleigh, North Carolina.
Wyatt was a 19 year old carpenters' apprentice.
He was killed in the first real battle of the Civil War, at Big Bethel near Newport News.
The Confederate commander was John Magruder, the Union Benjamin "the beast" Butler.
Union forces outnumbered Confederates more than two-to-one, but it was a Confederate victory, with the Union suffering over 18 killed, 53 wounded and 5 missing.
Confederates lost Wyatt and 7 wounded.
Remember too, in Lincoln's first inaugural address, on March 4, he promised secessionists that there could be no war unless they started it.
And Lincoln was true to his word, but secessionists were eager to get started and soon moved to make it happen.
Every tyrant who wins a war always paints a rosy picture of himself and vilifies the defeated.
