Is unequal to basic services reason enough to commit crime in south africa?

I would be very skeptical of a phrase "reason enough to commit a crime" - a "good" reason to commit a crime is a very debatable thing.

But think of it like this, if the unequal basic service access means for example access to clean water and a father decides to steal some bottles of mineral water from a shop for his sick son, then he was motivated by the lack of access to clean water (while some people living in a rich areas might have clean water running from their taps) - so in some cases, yes, might be a reason to commit a crime.

This really depends on the context and the particular situation.
