I wouldn't want anders to die at some point if I let him go or ask him to join.
I saw a youtube that templars bowed and some mages are spared.

You can get Anders to side with the templars if you are at full rivalry and have chosen the right dialogue options... but he'll kill himself in the epilogue, so you'd better be sure that's what you want to do.
All that is needed to become viscount is to side with the templars at the end, if that's your thing. You will have the option of sparing some apprentice mages and Bethany, but at that point, you'll have already killed a lot of innocent mages, so whether that concession rings hollow is up to you. Personally, I can't.
