nobody wants to judge you or your actions, applesthecat.
but you questioned what the community thinks so there might be different opinions.
if someone says it's a matter of honour not to sink hospital ships one states only his point of view.
if you like this tonnage do it! you are not killing real people.
but pls be aware that some others won't because they think it wouldn't be right. even in hardest battles.
and I might add:
not all of the u-boat commanders had high standards of morale and honour all the time.
so it's just up to you.
