Good call. Yes, the flag on a ring terminal is often shaped
to accommodate wire dress but a bend as sharp as 90 degrees
happens waayyy down on the s/n curve for failure (stress
versus number of cycles). Don't read any imminent risk for
failure here . . . you can probably bend and straighten the
thing out several times before failure. I just put an 8AWG x
1/4 terminal in a vice and 'stroked' it 8 times before I
could detect a reduction in resistance to bending. Failure
probably started at about half that number of strokes).

You've got a lot of headroom for cycles to failure under
the expected vibration levels but putting that 90 degree
bend in it cuts a humongous headroom number to a simply
big headroom number. But as Bob has suggested, do it
only once.
