For those of you who claim that the right thing in this situation would be to turn the child over to the authorities - what exactly do you think the authorities are going to do to make this situation better? The child obviously has some darkness that he needs to work through - to work through darkness he needs the support of a loving community.

You are calling a 17 year old person a "child". This is wrong, and perfectly in keeping with the trend of failing to raise children into mature adults.
17 year olds will be able to vote on their next birthday. They can hold jobs, they can drive cars, they can fly planes, they can even serve in the armed forces with their parents' permission. 17 year olds fought in the battle of Iwo Jima.
Calling this person a child diminishes them, and takes away their capacity for agency and responsibility. A big part of being a healthy, functional adult in society is responsibility. You can nurture them within a loving community all you want but if you protect them entirely from the consequences of their actions they will never become anything more than children.
