If I can avoid killing the wildlife I will. Unfortunately you seem to get attacked on sight. If I can outrun the bear, then may be I will. Alternatively, if I can see the bear in advance and choose whether or not to attack it, so much the better.
I have to admit that it seems laughable at times how easily you can loot chests, even right in front of people. I rather liked the system in Baldurs Gate, where in towns if you started breaking into properties and looting chests, the guard would actually turn up to arrest you. In other games you can break in but if you make too much noise, it will get you into trouble. On the whole in the Dragon Age games I adopt my own morality, so I may check out a chest in case there is something important there, and to get experience points for unlocking it, but if it is just a few coins or whatever and in a peasant's house, I leave it where it is. On the other hand, if it is a noble's property or a rich merchant, etc, I adopt the Robin Hood approach.
I tend to be polite to people because that is how I prefer to play it. Occasionally I am less kind, usually with slavers or people who have shown themselves to be sadistic bastards.
I like to get to know people before I sleep with them. Occasionally I have got myself into trouble by flirting when I didn't really intend it to be serious which has led to some awkward encounters, so I'll probably adopt a cautious approach in DAI and only flirt when I mean it, unless of course I decide to play an outrageous flirt and to hell with the consequences.
