Karma pahla question

Sri Tulsidas said: "Our destiny was shaped long before the body came into being."

Could it be right dat tis our body dat carries out the physical realization of dat destiny? Butt cos tis a physical realization in da current world, can we influence it with our free will

For example, if there is a certain amount of negative karma to be carried out by a soul, it would be different the way da person will have to act out dat particular karma according to his or her current physical reality aight. For example, through hard work n all dat shit or whateva, a certain soul has become a doctor. Another soul who had similar overall opportunities n shit didn't exercise his free will towards that cause n does some other shit n turns out to be a gangsta. Now say these souls were both supposed to live out 'equal amount' of karma related to financial hardship. Maybe the doctor may have to experience 'financial hardship' in a sense created by that self! Da gangsta may have to experience 'financial hardship' in a physical environment created by his gansta-self followin the same principle.
Here although it is da 'same' karma dat has played out, cos of free will, da doctor has created an environment where he would ride out da same karma on an relatively (and absolutely? as well) lesser 'physically demanding' level innit?

U don't need to leave your comments cos I know ur worried about saying somethin that seems less intelligent n all :)
