And a quick lesson from Skyrim:
If you leave no witnesses behind, you're less likely to be held accountable.
I was thinking about this on the weekend - what if you had a D&D setting where the gods, or fates, or what-have-you, really were watching all the time, and where your deeds actually did matter, even if there were no witnesses? I mean, sometimes it seems like D&D, this is how it is - but it only really matters when you die, in deciding where you end up temporarily (if even that), because D&D has a sort of quasi-Catholic afterlife, one where heaven or hell are more like Limbo, and eventually you pass on beyond even those (certainly in most 2E or later cosmologies).
What about a setting where the gods really were watching over people, really were helping them where they could? Really were pushing agendas? I don't think any setting really has much of that, and it might be cool to see one not where the gods were dead/banished, but where they were more present.
In such a setting I'd have all Divine power be Divine power, though (and thus radiant), even when used by evildoers for evil - Infernal power, from demons/devils/etc. would be necrotic etc.
Just thinking aloud, as it were.
I once played with a DM who used the following for chargen: you have a pool of two of every number from 8 to 18. You could choose any numbers for your stats, but until you exhaust the pool, you had to use only the remaining numbers for your next character.
Cool idea I thought.
Seems like Mr 8/8/9/9/10/10 and perhaps his older brother 11/11/12/12/13/13 would both "accidentally" meet their fates very very quickly with most groups!

One could dumpstat int/wis to excuse such shennanigans, too!
