Alright, possible answers:
If you kill the tip, it will reset the counter, so it will not grow anywhere so long as you keep hacking at the tip every turn. You could conceivably take a turn off and turn your sword elsewhere to get a stray roach or something, and, supposing the tentacle didn't grow anywhere inconvenient while you were swinging your sword back to face it, you could go back to whacking it. I am quite stressing the fact that it grows every other turn; if it grew every turn, it would be like a snake with several super-powers, and thus too hard. Every three turns, it would be easy as pie for Beethro to kill it without ever being in danger of attack. One is too hard, three is too slow, two is juuuuust right.
OK, add a couple rules here. If the tentacle only has one end attached AND it is right next to Beethro AND it will grow on the next turn, then yes it will go for Beethro. However, this would make no difference if Beethro were to swing his sword and kill the tip, thus thwarting its plans according to the order of code execution. So in short, if Beethro's death is inevitable, the tentacle will strike. Diagram:
WW are walls
TT is tentacle
* is tentacle tip
R is a roach
B is Beethro, lines are his sword
WWWWWWWWWWWWWWWWWWWWWWWWWWWWW
W W
WTTTTTTTTT W
W T W
W T W
W TTTTT*B R W
W / W
W W
W W
WWWWWWWWWWWWWWWWWWWWWWWWWWWWW
As you can see, the tentacle has been trying to reach the opposite wall, it may have been blocked by other creatures or Beethro's sword in its path. Notice that Beethro's sword is in a position to kill the tip, and we will assume that the tip will move on the next turn.
If Beethro turns his sword towards the tip, and destroys it, then the thought of killing him has never entered the tentacle's mind. When he killed it, it was still thinking about getting to the wall.
If Beethro forgets that it is the tentacle's turn to grow, and instead turns his sword the other way to deal with the roach, then the tentacle will seize the opportunity and kill him.
Remember that the tentacle treats Beethro's sword as any other wall. Also, consider this point: After a tentacle has latched onto two places, it will go for Beethro, going around walls to get to him. This means that the only time a tentacle will have more than two bases is if Beethro traps it in a dead end, thus forcing it to form a new base and grow a new tip elsewhere. (unless none of the three obstacles used are walls, in which case the tentacle tip will wait patiently until one of them is removed, which could be never if the obstacles are pits)
Also, I should say that they don't latch onto doors, because they know them to be unstable and not safe for forming bases.
