It's simple. Can you answer the following two questions?
>the origin of humanity, and
>what happens to the consciousness, when the heart permanently expires and the brain permanently decays?

If you can't - like absolutely every single person who's ever lived, then nothing is off of the table. NOTHING. That means, technically, you can do whatever the fuck you want. If you can accept the consequences, of source.

Many religions will tell you that "revenge is bad", but can any cunt who follows ANY religion, give you the answer to either of the aforementioned questions? Religion is BASELESS.

Never said that, faggot. It just means I don't know along with the rest of you. But I'm willing to consider possibilities. Meanwhile OP, maybe you want to write down the pros and cons - realistically - of your future actions. Then act accordingly.

Happy hunting! (Or lack thereof.)
