Batman/Superman: Did Superman kill the Kents?

About 3 issues ago when the aliens on this world were turned against Earth for the coming of the aliens who were lied to by What’s-his-face with purple skin and 3 eyes (he was on the Justice League animated show), Superman flew to the Kent farm and was in their kitchen with blazing red eyes saying something like “It ends NOW!” and the issue ended…what happened? Did he kill them or just tell them how he rejected Earth as his home?
