lincoln was pretty much the 1st one to throw the constitution over for the sake of the country and war. guess those points can be argued over and over. sometimes when you separate the legal argument from the moral one, you end up with two completely different points of view...
and as much as the war has been made to be believed to be about freeing slaves - it was about unfair interstate trade and the prevention of the south from marketing it's products internationally. Lincoln issued the emancipation proclamation after secession - legally the same as us telling Germany - anything)
true. slavery was pretty much on the way out already. as industry grew in the north and there were the beginnings of mechanized farming practices, keeping slaves was becoming less cost effective. also, the black slave trade was drying up along with the white slave trade from europe. it was even harder to come by indentured servants as travel became easier and ships more frequent.
