Yes, that is a good idea.
Actually flawless genius, too :>
Not only do you get a cool friend to have a few drinks with every Friday at the pub, and someone to talk to who also shares your rage at how fundamentally-flawed the world is, you also get an excellent and well-seasoned ally that will back you up in case you get in a fight!
All because you gave Kratos a flagon of delicious ice-cold Guiness beer!
