If you could teleport, why would you teleport there anyway? If Aulus could teleport, he would teleport not-there. That's the way things generally work with normal humans - if the Grim Reaper happens to be up this road, and I happen to have the ability to teleport, I will not teleport into his lap. It's basic human common sense. In fact, no. It's basic living matter common sense. The only things in existence that enjoy tumbling towards certain doom are asteroids and other dead matter. Oh, and humans. Whales too - but at least they tumble in such a way because they're old and bald and can no longer go for a tumble. There's a method to their madness.

Any other creatures that perform ritual suicide?

Many animals that appear to be depressed or grieving begin to exhibit self-destructive behavior that sometimes ends in death.[2] In 1845, the Illustrated London News reported that a Newfoundland dog had been acting less lively over a period of days before being seen "to throw himself in the water and endeavor to sink by preserving perfect stillness of the legs and feet".[2] Every time he was rescued he attempted to do this again before he finally held his head underwater until death.[2] Other dogs, as well as ducks, have also drowned themselves.[3] One duck did so after the death of its mate.[4] At Overtoun Bridge in Scotland, many dogs have been known to leap to their deaths; although long reported to be suicide, many scientists have now attributed it to the smell of mink.[5] Some dogs will refuse food after the death of their owner until they die as well.[4] In 2009, 28 cows and bulls mysteriously threw themselves off a cliff in the Swiss Alps over the span of three days.[6] One deer leapt from a cliff to its death so as to avoid being captured by hunting dogs.[4] Another famous example of animal suicide is the case of the dolphin which most often portrayed Flipper, on the 1960s television show Flipper. According to trainer Richard O' Barry in the film The Cove, Kathy, the dolphin, drowned itself before him.[7] Suicidal behavior has been observed more in female animals than male and in more vertebrates than invertebrates.[8]

Cows mindlessly throwing themselves over cliffs. Dolphins drowning themselves. Dogs jumping towards certain doom because damn that mink stinks. What a world.
