Scattered Space is not necessarily T1

Theorem
Let $T = \left({S, \tau}\right)$ be a scattered topological space.

Then $T$ is not necessarily a $T_1$ (Fréchet) space.

Proof
Let $T = \left({S, \tau}\right)$ be a non-trivial particular point space.

From Particular Point Space is Scattered, $T$ is a scattered space.

From Non-Trivial Particular Point Topology is not $T_1$, $T$ is not a $T_1$ (Fréchet) space.
