Unable to execute Scenario 2 in cucumber

Scenario 1:

Step1 - Login into the application - Pass

Step2: - Pass

Step3 - Fail

Step4 - Logout from the application (skip)

Scenario 2:

Step1 - Login into the application - Pass

Step2: -

Step3 -

Step4 - Logout from the system

Here In Scenario 1 > Step4 skipped, So application not logged out. 

So Scenario failed. 

How to handle this case and make Scenario 2 execute?
