I know it's not so good for me to drink Monster energy drinks, but now they're Satan's product?

No calories ... no sugar ... "Must be!!"

Did he like buy them out or sumtin? 

never heard of that but they might be bad for people that have heart problems, i tend to drink a lot of coffee myself

Hi WelbyQuentin. I drink them sometimes when they are on sale. Each person has their own conscience. If they really were made for some sinister purpose and I had knowledge of it, I would likely abstain. If it bothered the conscience of one of my brothers, I at least wouldn't drink them around them. Just me personally. Here's some verses that have principles that may or may not be of help:

(1 Corinthians 8:1-13) Now concerning food offered to idols: We know we all have knowledge. Knowledge puffs up, but love builds up. 2 If anyone thinks he knows something, he does not yet know it as he should know it. 3 But if anyone loves God, this one is known by him. 4 Now concerning the eating of food offered to idols, we know that an idol is nothing in the world and that there is no God but one. 5 For even though there are so-called gods, whether in heaven or on earth, just as there are many “gods” and many “lords,” 6 there is actually to us one God, the Father, from whom all things are and we for him; and there is one Lord, Jesus Christ, through whom all things are and we through him. 7 However, not all have this knowledge. But some, because of their former association with the idol, eat food as something sacrificed to an idol, and their conscience, being weak, is defiled. 8 But food will not bring us nearer to God; we are no worse off if we do not eat, nor better off if we eat. 9 But keep watching that your right to choose does not somehow become a stumbling block to those who are weak. 10 For if anyone should see you who have knowledge having a meal in an idol temple, will not the conscience of that one who is weak be emboldened to the point of eating food offered to idols? 11 So by your knowledge the man who is weak is being ruined, your brother for whose sake Christ died. 12 When you sin against your brothers in this way and wound their weak conscience, you are sinning against Christ. 13 That is why if food makes my brother stumble, I will never again eat meat at all, so that I will not make my brother stumble.
(1 Corinthians 10:25-30) Eat whatever is sold in a meat market, making no inquiry because of your conscience, 26 for “to Jehovah belong the earth and everything in it.” 27 If an unbeliever invites you and you want to go, eat whatever is set before you, making no inquiry on account of your conscience. 28 But if anyone says to you, “This is something offered in sacrifice,” do not eat because of the one who told you and because of conscience. 29 I do not mean your own conscience, but that of the other person. For why should my freedom be judged by another person’s conscience? 30 If I am partaking with thanks, why am I to be spoken of abusively over that for which I give thanks?

This has been around for some years.  It is either a snappy sales appeal or a craziness of the original poster.

No.  I don't think anything of the sort.  All of that is noise.  And the chief thing I think is that that potion can and does wear on the adrenal glands.  That is what gives us energy.   The glands sit atop of the kidneys.  It can wreak havoc with your sleep patterns, age you, mess with your skin.  So, in that context it kind of is Satanic.

LOL  You know, instant gratification of energy and lessening the need for food, in exchange for wanting more and more of it and sleeping less and less.

But those symbols and such are the product of messed up minds drinking way too much of this stuff.

They are speeding their asses off and getting paranoid just like methamphetamine does to the body.  

SATAN. 

They're terrible for me, but I still drink them anyway. I like Rockstar better, Monster reminds me of beer for some reason. And, yes, I have heard of the Satanic conspiracy theory, but it's all BS. You may like this one, however:
