Yet sinkies endorse the stealing.
So I can conclude, morality is absent in them.

that is insufficient evidence to conclude about absent morality. and for all sinkies. It is accurate to say that it is deficient, mistaken or lacking, but absent is a logic leap. As it is for all sinkies.

Wouldn't be a surprised if they sold their mom for some cash when it comes to it.

while true for some people, that does not make a conclusive statement regarding sinkies. Sure some sinkies will sell their mothers, others will endorse something lacking in ethical substance. But to jump from self-concluding one observation to the next is false logic. This kind of circular and self-supplying logic is what religions like Judaism feed and subsist on.
