Would toi rather know how to hypnotize someone ou know how to resist hypnotizing/brainwashing tactics?

i seriously want to learn what this girl do in Avengers:Age of Ultron

I Would Rather Know How To Hypnotize Someone.It Is plus Fun Brainwashing Different Kinds Of People Than Just Resisting To It.Besides If Another Person Has The Same Ability It Will All Come Down To Who Has The Strongest Mind !!!!

I can already resist the governments hypnotizing/brainwashing tactics.

If i knew how to hypnotize others, i could reverse engineer the ability and find out how to resist it anyway!
