Could angels deviate from their entrusted mission while on earth?

[tonychanyt]

Yes, that's one way for them to sin, Job 4:

18 If God places no trust in his servants,
if he charges his angels with error,
19how much more those who live in houses of clay,
whose foundations are in the dust,
who are crushed more readily than a moth!

The same idea was repeated later in Job 15:

15 If God places no trust in his holy ones,
if even the heavens are not pure in his eyes,
16how much less mortals, who are vile and corrupt,
who drink up evil like water!

An angel vs angel warfare was described in Daniel 10:

13 But the prince of the Persian kingdom resisted me twenty-one days. Then Michael, one of the chief princes, came to help me, because I was detained there with the king of Persia

The prince of Persia either had deviated from his initial entrusted mission or soon afterward while Michael had not.

Paul warned in Galatians 1:

8 But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed.

2 Pet. 2:

4 For if God did not spare angels when they sinned, but cast them into hell and committed them to pits of darkness, reserved for judgment.

Jude 1:

6 And the angels who did not keep their positions of authority but abandoned their proper dwelling—these he has kept in darkness, bound with everlasting chains for judgment on the great Day.

Angels fought against angels in Revelation 12:

7 war broke out in heaven: Michael and his angels fought against the dragon, and the dragon and his angels fought back.

There was a period of time when some angels deviated from their entrusted mission and sinned. They followed Satan and fell from God's presence. By now, angels have been separated into two camps. The good angels would not deviate from their entrusted missions.

Or their entrusted mission was to sin.
