Lifeboat ethics - Real Lifeboats!

[Leanne]

yes but they're will be times in some sea
catastrophe where lots of people are trying to get into too few lifeboats
both on the stricken ship and in the water.

Yes, but there will still be fat ones to eat first

I agree with velvetfog, start paddling as soon as the boat is full and move out of the range of the stragglers. Then you're not actually killing them... there's still a chance they'll catch onto some passing debris and avoid the sharks until rescue arrives (not a big chance, but still). Altruism really only works on paper.
