Thornless Honey locust disease

[hageyb3]

Hi! I was hoping to get help identifying this disease and see if this tree is worth keeping or if cutting down is the best option. It was not planted in the best location, and some of the bark has turned black or fallen off. There's also some interior dead wood. Recently a limb broke in a storm, so I had to saw it off and included a picture of the cut as well. Thanks!

Hard to tell from the pictures but the problem is simple rot where the tree has tried to occlude the initial damage but something, presumably squirrel, has been nibbling at the phloem of the wound wood.

 

Picture attached, the initial wound in pink, the wound wood attempting to grow over the wound and green the extent of decay from organisms that entered the tree following the initial wound.

 

Can you make out teeth marks on the bark of the wound wood?
