Because it would abolish slavery in all of the new territories; territories that were acquired from the Mexican War

The Kansas-Nebraska Act of the U.S. Congress said voters in these territories to choose whether they would allow slavery or not. Thousands of antislavery northerners went into Kansas and voted to forbid slavery, then returned home.
The Mexican-American War caused an internal dispute in the United States government over slavery. The Northerners did not want slavery to spread into the new territories if they were annexed into the United States, while the Southerners wanted the territories to have the right to decide.
True. There were some northerners who believed that if slavery remained in the South and did not spread to the new territories, it could eventually die out on its own. This viewpoint was known as "free soil" or "free labor" and was held by some abolitionists and moderate opponents of slavery.
Some northerners believed slavery was morally wrong. Southerners believed slavery was an essential part of their lives.
Northerners mostly agreed on the importance of preserving the Union and opposing the expansion of slavery into new territories. They believed that allowing slavery to spread would undermine free labor and threaten democratic ideals. Additionally, there was a strong sentiment for civil rights and moral opposition to the institution of slavery itself among many in the North.
Northerners feared that southern slave owners would expand slavery into new territories, leading to political and economic conflicts. They were also concerned about the influence of pro-slavery forces in the national government and the potential spread of slave labor competition in free states.
Some Northerners objected to dividing the Nebraska Territory into two separate territories because they feared it would promote the expansion of slavery into new western territories. The proposed Kansas-Nebraska Act allowed for popular sovereignty, meaning that settlers in each territory could decide whether to allow slavery. Many Northerners believed this would undermine the Missouri Compromise, which had previously restricted slavery's expansion north of the 36°30' parallel, and they were concerned about the potential political imbalance it could create in Congress.
Northerners were completely against slavery, and before the Civil War they took their hatred overboard by killing Southerners for their slavery.
