Comparing two files with simple answears, summing them up with no output to console

I have two files as atributes in my script with ten lines in each. They contain simple answers: YES or NO. I need to compare those two files and get number of good answers and bad answers. I need to have them in separate variables. I have tried :

diff <(nl $1) <(nl $2) | grep -E '<' | wc -l

and i get number of bad aswers, but i want it to be in some variable.
