That dramatically changes the meaning/feeling of the song (depressing in the latter, as intended - inspiring in the former, in an "overthrow" sort of way).
Although it would explain the stupid (in my previous understanding of the lyrics) juxtaposition of the line "When you can't really function you're so full of fear" just prior to the main lyric (two lines in a row ending in "fear", silly).
Anyway, CARE.
