[Superman] Would the Silver Age Earth-1 version of Superman killed Doomsday?

Most heroic versions of Superman would not kill except under the most extreme circumstances. For example, the Golden Age Superman of Earth-2 killed a few criminals in the late 1930s, but then promised to never kill again, but then killed the Anti-Monitor. The post-Crisis version used Kryptonite to execute the Pocket Universe's Phantom Zone Villains, then swore to again never kill, but then was forced to kill Doomsday a few years later. 

The Silver Age Earth-1 version however, probably the most powerful version, never killed and adamantly refused to. (This is not counting Alan Moore's "Whatever Happened To the Man of Tomorrow?" where he killed Mxyzptlk, as this was only an Imaginary Story.) Would he have killed to stop Doomsday?

Silver age superman would find some way of imprisoning Doomsday without killing him, he would use super-orbital calculations to throw doomsday into an orbit where he was frozen in stasis around some stars that Superman moved there earlier just for this purpose.
