I can see why an argument is going to develop here. The reason is that different people train for different reasons and also there is a real difference in philosophy between different styles.
I didn't start aikido to become a better person and yet I believe I am now - if you train properly in the right company you cannot help it.
If you do aikido just to fight, you will only limit yourself - aikido is much more than just that. But you should feel that you could use it if you needed to.
Aikido is like having a big muscular girlfriend. She takes all your time, and makes you give up all your weekends and tires you out, but if anything ever happens, she'll always look after you
