'Shamefully' in the Bible

The rest [of the invited guests] seized his servants and mistreated them [insulting and humiliating them] and killed them.

Again he sent them another servant, and they [threw stones and] wounded him in the head, and treated him disgracefully.

But Saul began ravaging the church [and assaulting believers]; entering house after house and dragging off men and women, putting them in prison.

even though I was formerly a blasphemer [of our Lord] and a persecutor [of His church] and a shameful and outrageous and violent aggressor [toward believers]. Yet I was shown mercy because I acted out of ignorance in unbelief.
