Answer:
1. Abolitionists used bible based references to show the moral decay associated with slavery as demeaning and ungodly.
2. Abolitionists showed that slavery permitted and exemplified human cruelty from one human to another.
Step-by-step explanation:
On the basis of moral decay, slavery was seen as morally degrading. The allowance of a human being to reduce another human being to nothing more than a property that could be bought and sold at the owner's whim was seen as one of the worst form of sin that could be committed on a fellow man. Abolitionists tried to prove this as not right and drew references and conclusion from the bible that this was not the way humans were intended or supposed to treat another. The abolitionist equated slavery to a big sin before God and man.
On the basis of cruelty, slavery justified the use of force by the slave owner to curtail or control his/her slave. Physical abuse and mutilation of slave was seen as a strong characteristics of a good slave owner. Constitutional laws were put in place to take care of disobedient slaves in the most cruel way possible, and deadly harm done on a slave was met with the mildest punishment as if it was done on a farm animal. Slave were not seen as been above farm animals.
