McGonagall's description:

[...] Everyone wished for something more to be done, and no one dared take the lead to propose it. Whoever stood out the most became the next example.

Until the names of James and Lily Potter rose to the top of that list.

And those two might have died with their wands in their hands and not regretted their choices, for they were heroes; but for that they had an infant child, their son, Harry Potter.
