I cut down a tree so it would fall on a house
Why would you want it to fall on a house?
I just did. I can't hurt a living being.
Someone lives there and depends on that place to stay protected and warm. That will cause a lot of damage and cost them a lot of money.
OMG, I did something bad. What can I do to fix it?
I would suggest going to the person whose house you damaged and explaining the situation, then offering to pay for the repairs. You should do what you can to make it so that the person has as few interruptions to their life as possible.
