It’s got a wonderful defense mechanism: you don’t dare kill it.

Our reading
An editorial interpretation.
The speaker calls a defense mechanism wonderful, then defines its effectiveness by the fact that nobody dares kill its owner. That reversal makes an apparent weakness into protection. The approving adjective can be read as dark admiration for a situation that leaves an attacker unable to act.
