I’m struggling to read your comment in good faith but I’m going to get there by saying that you don’t travel and are repeating hearsay as fact. If you have an international inbound flight which includes a transfer in Europe, it doesn’t matter where you embarked or what the security regime was like. Whether you have to recheck your bag depends exclusively on whether your transfer is at the same airport and your airline’s policy (eg Ryanair make you pay extra not to have to recheck). In general in Europe you only clear customs at your final destination and at tge airport you transfer to leave Europe but this wouldn’t apply if you need to transfer at a different airport or between two airlines that don’t have an agreement. It certainly never depends on the European transfer countries opinion of security at your country of embarkation.
