"Those who hate cats will come back as mice in their next life."

Think about this:
If reincarnation was real... would you come back in the next life with previous knowledge and memories?

If yes, than it's impossible to reincarnate as a human, as you would be born a baby, and if you had the knowledge and memories of your previous life, you would be able to talk and share memories of your past life. That only lets you reincarnate into anything that is not a human. Say you turn into an animal... animals may not have the ability to speak like humans, yeah? So then you'll just be an animal dying to share with everybody, even humans, what you know and you want to tell everybody that reincarnation is real. But that would suck because you can't communicated like you were a human. There's a lot more points we can all make, just think about it.

If no, then what exactly is the point of reincarnation? If you have no memories or knowledge of your past life, then you're barely yourself. Reincarnation would not be real, because you're personality, memories, knowledge, and characteristics make up WHO YOU ARE, as an individual. Without these things (which you had in your past life) you would be somebody completely different. Which means it's not as much reincarnation as it is simply a NEW LIFE starting.
