Fable II

The easiest and quickest way to get to 100% good is to give the gold to a beggar instead of donating it to the Temple of Light.

I noticed that for each donation to the Temple of Light there's a maximum of 75 good morality points. This means a lot of donations to get to 100% good. However, there is no such limit when giving the gold to a beggar which means that the more you give gold wise, the more good morality points you'll get. So in one (hefty) donation to a beggar you can get from 100% evil to 100% good at once.

If you're looking for a beggar you can find one sitting near the end of Bowerstone bridge.

The fastest way to do this would be to reach full evil by killing a lot of innocents. To do this you need to turn safety off from the expressions menu, the lower left choice just after hitting RB, sometimes comes up on the shortcuts as down.

To reach fully good, your only real hope is the Temple of Light donations and quests. Raising to full good by donating to the Temple is a very long process and probably will make you want to break the game disc in half. Really if you are wanting to be full good, for your own sanity, rely on making good choices during the quests.

If you haven't made much money yet it is easier to get this by killing innocents. I tried giving money to the beggar but after about 50000 I was still only half way to getting full good.

I saved my game first and then I turned safety off and started shooting innocents. It felt like I was playing GTA. I got full evil after about 5 minutes and the achievement popped. Next time I played I just loaded my saved game and my evilness was gone.

It's not difficult to get 100% good if that's what you're going for (despite other guides seeming to favor going for 100% evil). Assuming you have made most of the morally good quest choices throughout the game, it just takes a little extra grinding in post-game to max things out. Easy ways to boost your good points:
- Doing "Slave Rescue" quests usually gets you about +30 each time, just look out for whenever one is available under the Quests menu
- If you are married, you get a free +20 every time you go back to visit your spouse. My marital home was in the middle of Bowerstone Square, which is a good central location that's easy to visit. Especially as you're popping back & forth for the archaeologist quests, just swing by your house each time you're back, walk up to your spouse and after a second or two the little angel icon will float over your head. If you're in the postgame with nothing left to do, just fast travel to some other location and then back to your spouse and you'll get +20 each time.
- Donating to the beggar on Bowerstone Bridge or in Bloodstone, but you only get +10 for each 1000 gold
