We can think of the servant that buried his talent here. Sloth is a spiritual lethargy that causes us to not advance in the knowledge of God.
I think we all suffer from this at times ....just think of the 10 virgins who ALL fell asleep.
We need to be awake.
There is a spirit called "rouach tardemah"
Is. 29:10 For the LORD has poured over you a spirit of deep sleep, He has shut your eyes, the prophets; And He has covered your heads, the seers.
Why would God do this?
Well, God is not going to chase us around to get things done. We need to go to Him. If we present a slack attitude to God, then He will send the waster.
The wicked servant in this parable was the only Good guy in the story. The man who goes away is Satan and the Wicked servant kept the money safe in line with the Law of Moses while Satan was away and did not use the money he was given to oppress the people around him. As such the servant who buried the talent did not have a spirit of lethargy nor was he a sloth. He was in fact advancing the knowledge of the kingdom of God to Satan his master at that time and to the people he refused to oppress.
Perhaps you need to consider more carefully the scriptures and your understanding before you post.
Shalom
