From her wiki: "...it is here revealed that the ship Oliver and his father were on didn't shipwreck but was sabotaged by Moira."
Reading g the whole wiki entry top to bottom it apoears that she is definitely 100% wicked and evil BUT tries to reform through season 2 and 3. She seems totally complicit and happy with it all until she relasizes merlyn controls her, not the other way around near the end of season 1, which is all I've watched to. Season 2 and 3 wiki as a redemption story of sorts.
I trust you as far aa I can throw you (my upper body strength sucks) but I need to preserve myself and being forced to read every episode description helps your case.

You're editing out the "unknown man" to better serve your purpose. What it really said:
"As the episode ends she is seen getting into a limousine with a unknown man , it is here revealed that the ship Oliver and his father were on didn't shipwreck but was sabotaged by Moira
and the unknown man."
The unknown man was Malcolm Merlyn and it is stated many times throughout the wiki that she was under her thumb and wanted him gone. Prior affair or not, she was forced onto his team and only went along enough to protect Oliver and Thea.
Also from the wiki:
"Moira is oftentimes ruthless, in an ends-justify-the-means sense. She had her own son kidnapped, but tried to justify it as doing to so prove he knew nothing about the Undertaking, and thus save his life. She attempted to have Malcolm Merlyn killed, so that she would be out from under his thumb, she and her children would be safe, and to prevent the deaths of innocent thousands. When the attempt failed, she betrayed her co-conspirator, Frank Chen, to avoid her own implication and so she and her children would not be killed. Malcolm, as The Dark Archer, killed Frank. Despite evident and prevalent flaws, it should be noted that Moira convinced The Dark Archer to spare Frank's daughter.
It becomes increasingly evident, as the series progresses, that Moira is in way over her head. After Oliver revealed how Robert really died, and how he sacrificed himself so he could live, she finally does the right thing, realizing she cannot live with the guilt of being an accomplice in killing innocent people in the Glades."
You didn't need to read every episode, just the general statement about her to get the whole story. Taking bits and pieces here and there will give you a skewed view.
