I′m currently at the beginning of my second Fallout 3 playthrough and would like to have Butch as a companion, but the neutral Karma requirement makes that difficult... staying neutral until I can first recruit him isn′t hard, but I inevitable get good karma at some point (although I steal everything in sight - and I don′t want to randomly shoot harmles people just to lower Karma), which is bad because at some points in the story - and everytime I start a DLC - I′m going to get seperated from Butch which makes it impossible to re-recruit him afterwards.
My question now is if this can be avoided - like telling him to wait before I get seperated or something like this.
If not I guess I′ll just stick to Charon who′s not so picky...

Edit: Oh, and I′m playing on PS3 - so I can′t install mods
