Desperate for help about intent and my fears
"Would I be committing these heinous crimes/sins if I don’t have any intention to kill/cause harm? Even if I willfully think something/say something and someone kills because of it – I don’t have intention to kill and in my heart I don’t want to hurt anyone. - Is my intention what counts? It’s what I am telling myself “I don’t intend for anything bad to happen."


In Buddhism, it's the intention behind an action that counts. It's the intention that's "kamma-potent" and what causes future effects to take place. 

Harming or killing another living being can only happen with an impure mind, i.e. a mind that acts with intentions of anger, hatred, ill-will.

If your intention is wholesome, i.e. based in renunciation, good-will, harmlessness and a sincere and honest wish to help other beings, then only wholesome future resultants will take place. 

Please read about "Right Intention (Samma Sankappa)", p. 26 in "The Noble Eightfold Path", by Ven. Bhikkhu Bodhi and the Twin Verses about "Intention", p. 58, in The Illustrated Dhammapada.
