Honor?

So with those all around, he would of had to have made a large blas to destroy those.

Maybe the pred didn't think that there was enough room, or it would have been awkward and Harrigan would have caused them both to fall. Idk,  Im grasping for straws here.

Maybe, this is just a theory, that was its' last night hunting on Earth (the predators leave after Harrigan kills the Pred), and it would look weak for not being able to kill the one human it had hunted for so long, so it decided to just destroy itself to save face...

But that makes another problem... if the self destruct devise had gone off, could it have destroyed the PREDATOR SHIP that was right underground, with all the other Predators in it?

Unless it was like was said before, the blast could have been made to be smaller, just enough to destroy himself and gear he left behind.

In both P1 and P2  the predators slide a scroll bar to the far end of a scale on their wrist-comps.  I beleive this sets their power-supply to maximum yeild.  Since this is done in both movies, it would have wiped out "10 city blocks," which may or may not have included the pred ship, depending on shielding and materials, etc.
