I think you accidentally posted the same code twice.

Anyway, we have no idea where aws_policy_effects, etc came from, so we cannot possibly say what order they're in.

Also, you can shrink that loop a lot:

Code:
STR=""
for X in "${aws_policy_effects[@]}"
do
        [[ "$X" == "Deny" ]] && STR="$STR DENY" || STR="$STR ALLOW"
done
aws_policy_effects=( $STR ) # Do not quote, splitting is intentional

...but it might have been easier to just pipe the data through tr 'a-z' 'A-Z' in the first place.

I'm sure that last block of code could be shrank too.

Probably all of it could use a good looking over and rewriting.
