Vengeance do you believe in it ? Why why not

I'm petty like that.

I've always served it back

It's been my observation that the one seeking revenge usually pays at least as dearly as the one being 'paid back.' Probably more so, because the one bent on revenge has to invest time and emotional energy in planning and executing the revenge.

Far better to spend all that on living well.

Most of the world's prison/judicial systems are based on it, on the whole it doesn't work to change behaviour. I understand it, have done/used it on a small scale. Idk.

As much as I enjoy it the thought of it, blood doesn't wash away blood. Then again, in some cases, who gives a fuck.

Absolutely not. I am a BIG believer of Karma tho. 😇

No, cuz Karma deals with that

Yes, it belongs to the Lord.
