What sorts of activities does the Devil describe himself doing?

From the text:

"Your grounds!" said Tom, with a sneer; "no more your grounds than mine; they belong to Deacon Peabody."
"Deacon Peabody be damned," said the stranger, "as I flatter myself he will be, if he does not look more to his
own sins and less to those of his neighbors. Look yonder, and see how Deacon Peabody is faring."
Tom looked in the direction that the stranger pointed, and beheld one of the great trees, fair and flourishing without, but rotten at the core, and saw that it had been nearly hewn through, so that the first high wind was likely to blow it down. On the bark of the tree was scored the name of Deacon Peabody, an eminent man who had waxed wealthy by driving shrewd bargains with the Indians. He now looked around, and found most of the tall trees marked with the name of some great man of the colony, and all more or less scored by the axe. The one on which he had been seated, and which had evidently just been hewn down, bore the name of Crowninshield; and he recollected a mighty rich man of that name, who made a vulgar display of wealth, which it was whispered he had acquired by buccaneering.
"He's just ready for burning!" said the black man, with a growl of triumph. "You see I am likely to have a good
stock of firewood for winter."
"But what right have you," said Tom, "to cut down Deacon Peabody's timber?"
"The right of a prior claim," said the other. "This woodland belonged to me long before one of your white-faced race put foot upon the soil."
