Ben Solo is going to get redeemed. You can count on it, at least if JJ Abrams understands even the smallest thing about the moral universe that George Lucas created in the first six Star Wars films. Redemption is as baked into the DNA of Star Wars as lightsabers and space battles, and to swerve away from that in the supposed final chapter of the Skywalker saga would be far more shocking than killing off all the characters at the end of Rogue One. Whether that redemption involves a love scene with Rey remains to be seen (don’t count on it), but by the end of the film Kylo Ren will have returned to being Ben Solo, and he will have found redemption.
