I would certainly resent those who keep telling you how much you should want/need/expect.
I'm don't understand this. All through this thread you've been saying the offer made was not enough.
Isn't that telling them "how much you should want/need/expect" ? Just because you want them to get more doesn't make offering your opinion any less intrusive than those who might think the offer is fair.
Everyone who has posted an opinion is doing just as you have... expressing an opinion. No one is telling anyone affected what they "should do". Those who were affected directly will make their own decisions in the end.
I'm guessing it will be some time before any of them make any decisions on negotiated settlements.
Regardless of compensation, they thankfully have their lives to live. Those families who lost loved ones will sadly feel that loss forever.
