What arguments could be made for supporting the Radical Republican view of adding further punishment?

The correct answer to this open question is the following.

Although the question does not provide options or further reference, we can say the following.

The arguments that could be made for supporting the Radical Republican view of adding further punishment to the Confederate States during the Reconstruction period were that the Confederate Army caused too much damage and destruction in the United States territory, as well as many deaths. These were enough reasons for radical Republicans to demand more severe punishment for the South. Furthermore, the South had not adopted the emancipation proclamation and still had many landowners who possessed slaves. Some other southern states did not grant civil rights to African Americans and it was notorious the racial segregation is the South. And of course, Radical Republicans were against this.
