Just Traded Geronimo/Ballage for Godwin/Green. Should I feel badly?

Well gents, I just robbed my league mate. I traded them Geronimo + Ballage for Chris Godwin. What make it even better (or worse depending on your perspective), my league mate then thought it was a good idea to drop AJ Green who I immediately picked up on waivers.

I’m obviously elated, but can’t help but to feel a little guilty for completely taking advantage of them.

What do you think? Do you feel badly when you win lopsided trades with less knowledgeable league mates?
