Jesus had a different view to evil. He believed that his cause was so good that evil could not be used to achieve it. He experienced terrible injustice and pain when he was beaten and killed on the cross at the hands of evil political and religious leaders, but he accepted it, because he believed that his cause was so good that it justified acceptance of terrible suffering in the face of evil. His cause was so good that evil could not be allowed to corrupt it. The end did not justify the contamination of evil.
Jesus called on the church to follow his example, but it has not always chosen to follow him. During the middle ages, the inquisition tortured heretics to keep the faith pure. The people doing this were not evil. They were good people using evil means to advance a good cause. The crusades are another example. The crusaders committed terrible atrocities when they invaded the Middle East, however their aim was to advance the gospel. They were ordinary people using evil means to accomplish a good goal.
Modern political leaders usually follow the same line. They believe their cause is so good that they are justified in using evil means. They are willing to bomb the crap out of Middle Eastern countries like Libya and Syria, because they are trying to advance the good cause of democracy and human rights. They are good people doing evil things to advance a cause they believe is good.
The Beast of Revelation will emerge in the same way. It will not be an evil person. It will be a good government, that believes that its cause is so good that evil actions are justified.
This attitude is prevalent amongst Christians in the United States when they talk about ISIS. The vehemence with which they speak about the violence and destruction that they would like to unleash against ISIS is scary. Their ferocity makes them sound evil, but they are not. They are good people who believe that their cause is so good (USA) that they are justifying in using evil to protect it.
Unfortunately people who believe that their cause is so good that it justifies actions are far more danger than evil people. Because despite the cleverness of the secular commentators, the spiritual powers of evil have not gone away. When good people use evil, because their cause is good, they open themselves up to these spiritual powers. Once they are given influence, these evil powers can get a stronghold, which allows them to do much greater evil. I fear that this is happening in Europe and the United States.
When the emerging Beast of Revelation had done some serious good, by using evil means, it will come under the domination of the spiritual powers of evil. It will be unable to do good even if it wants to.
The people of ISIS did not set out to do evil. They were good people who believed that their cause was so good, that they were justified in doing evil. Once they had done a little evil to achieve good, the powers of evil got a stronghold, and their evil got worse, but they still believe that their cause is good. They believe their cause is so good, that terrible evil is justified.
I worry about any group who believes their cause is so good that it justifies the use of evil means. I feel safer with Jesus, who believed that his cause was so good that it must not be contaminated with evil.
