What are some idioms that would describe a scenario where two people agree on an idea- but for very contrasting reasons?
Scenario 1: Two classmates support the demolition of an abandoned factory: Alice supports the demolition because it's going to be replaced with a public park. Her classmate, Sid, supports the demolition because he's loves explosions and is eager to watch the building get destroyed.
Scenario 2: Two people with opposite political views admire the mugshot of Donald Trump: The first person enjoys it because they dislike the former president and find his prosecution to be satisfying. The second person likes it because they support the former president and the mugshot boosted his poll numbers and enhanced his persona.
Both scenarios are semi-fictitious and meant for demonstration.
