If the tree is dead or rotting then it is better to cut it down. If you're unsure of the status of a tree, you should be cautious around it until it has been tested. Basically don't climb it or put a swing on it. I am not sure what the point of point 2 is, when you have point 1. You don't really have to cut down all the untested trees on your property, but if you're not doing testing/maintenance on the trees for ANY reason(ignorance, cost), don't be surprised when one kills someone and you're held liable for it. You should consider this before buying a property with trees. It's similar to owning a dog. If you own a dog, and it runs out and bites someone, you will likely be held liable, and the dog will likely be put down. If the dog tests positive for rabies before even biting anyone, it will be put down, similar to a dead tree being cut down.
