Not really, only sometimes i think about this but i hope that they will have lifeboats to survive, but in rough waters and in the middle of the atlantic...
Some time i killed with three torpedoes more soldiers at once than using several panzers and artillery in the battleground.
In the mediterranean i´ve found two troop ships scorted by a scort, after i sunk the destroyer and damaged every troop ship with one torpedo , i surfaced and started firing with my 105 mm gun.
imagine the scene... the ships burning in flames, sinking, the lifeboats in the water( i supose it ), the shells exploding in the crowded decks, my 20 mm and 37 AA guns firing at will,
After some minutes the troop ships sunk in the middle of a huge cloud of smoke and fire.
i killed a lot of people but i´m not a murderer.
