While I understand the desire to be kind and gentle to everyone, this is a game about murder where you get a majority of your experience from killing things. There are probably better games out there for you if this isn't the tone you are looking for. I'm not trying to be dismissive here, but honestly something like Undertale may be closer to the tone you are looking for. It has the option to both be a murderer and be extremely kind. If you haven't played it, give it a try. It's a modern classic.
Regarding the fallout comments, 1 and 2 definitely had some of the best dialog and impactful options of any game, with New Vegas right behind them. But 3 and 4 had maybe 5 consequential choices between the two of them.
