Henry V was like that, too. He was fickle in his alliances and friendships, casting aside those who had doggedly served him, and reducing them to penury and oblivion.
Here, from Henry V, is Wolsey's lament at the sudden end of his career:
here take an inventory of all I have,
To the last penny; ’tis the king’s: my robe,
And my integrity to heaven, is all
I dare now call mine own.
O Cromwell, Cromwell!
Had I but served my God with half the zealI served my king, he would not in mine age
Have left me naked to mine enemies.
Don't leave yourself naked to your enemies. Serve God first.
