Love, without a doubt. Given that the Love card also revived your spouse and child (if it didn't glitch like it did to my family >_>) I think anyone with a family of their own would pick the Love card. Even a psycho like Kratos valued his family over power.
And I know this is off topic, but on the point of Kratos, if he can walk in and out of hell, and visited heaven, AND became a fucking god, WHY couldn't he have just resurrected his family rather than brood and kill???
