RAW has its ups and downs. Helping Others is "the first word" on Good in PHB. But that doesn't have to include evil characters, though it can.

the "if it helps you as well, or comes at no cost to you, its Neutral" bit is a bit dubious. Still, the "helpfully courteous" person is more a very nice Neutral than a Good type.

On the bright side, the "self-sacrifice" comes as a subcategory of helping others, and the "doesn't have to be evil others as well" bit needs to be remembered.

An evil minion who dives in front of his boss "For the Greater Evil" is not getting a free pass to the Upper Planes.
