There are two types of things in the Universe, which are living while the others are non-living. The non-living things are at rest or in their motion until they are disturbed by others body, these non-living things do not alter their own way of motion only if they are in motion. Hence, until some external forces or entities don't disturb the normal cycle of the non-living things till that moment the cycle of non-living things aren't getting diverted from their path. But when these non-living things have random motion then they don't come to stable path until external forces act on them. Hence, we can say that non-livings do not have their will to change their own cycle. Hence, these things aren't related to the concept of "FREEWILL", but these things can be determined.
The past & present observations can help to make hypothesis & then by scientific method we make these hypothesis turn into law. These laws are capable of telling the probability of the non-living thing's existence & their future position or path. On the basis of these laws we can predetermine the world around us with firm basis, but the most important entities in these predetermine world will be non-living things.
Animals & especially humans are the living organisms who can use their brain for thinking. The can decide upon things to be done by them in their near future, only if those things satisfy their materialistic or spiritualistic things. In case of humans, things they do depend mostly either on their thinking or on their emotions. One cannot say that things done by humans are determined because humans decide mostly when they face those kind of conditions. Until then they jus make assumptions about their own behavior. Normatively it is thought that people do not have their freewill because the have to undertake those activities that are forced by their society. But when it is thought rationally it can be concluded that this is a false image that has got fixed in everyone's perspective. People have their freewill as they are allowed to decide upon the things that are necessary for them. The society norms are for namesake as they don't directly affect the freewill of the individual person. In difficult & extreme situations people don't at all think about the norms of the society because in such conditions they are the real ones who face the conditions. Hence, the thinking & actions of the humans are not predetermined, but the same people have their freewill.
